de Finetti risk seminar - aprile 2014

02 Apr '14

On behalf of the Scientific Committee of The de Finetti Risk Seminars - on the Mathematical Theory of Economics and Finance in Milano, we are glad to invite you to participate at the "de Finetti Risk Seminar" on April 9, 2014 at 18.00 with the Lecture Equilibrium in risk sharing games COSTANTINOS KARDARAS London School of Economics Abstract: We study equilibrium sharing of investment risk among agents whose random endowments constitute private information. Given the sharing rules that optimally allocate the submitted endowments, we propose a Nash game where agents' strategic choices consist of the endowments to be submitted for sharing. It is proved that the best response problem admits a unique solution (which we call "best endowment response") and differs from the agent's true risk exposure. Then, we proceed in showing that the Nash equilibrium risk sharing admits a finite dimensional characterisation, and that it exists and is unique in the case of two agents. Analysis shows that the game benefits the agents close to risk neutrality, since their expected utilities are higher at the Nash risk sharing equilibrium than the optimal risk-sharing one. (Joint work with Michail Anthropelos.) LOCATION: The seminar will be held on Wedsnesday, April 9, at 18.00 at Sala di rappresentanza, Department of Mathematics, Milano University, Via Saldini 50, Milano.

Ciclo di Seminari - Progetto ERC PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 7 aprile ore 14 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Jean-Marc Azaïs IMT, Universite de Toulouse, France Title: The tail of the maxima of Gaussian fields on non locally convex sets. Abstract: The Euler Characteristic method or the Rice method give a full expansion of the tail of the maximum of stationary Gaussian fields defined on some regular sets. A key hypothesis is local convexity that means roughly that, by a smooth change of parameterization, the parameter set can be transform in a convex set. In our talk we will present an alternative method that works for general parameter set as fractals sets and permits to obtain a full expansion in dimensions 2 for a large class. Our result will be illustrated by examples that are all new. Tutti gli interessati sono invitati a partecipare. ................................................................................

For such fields, we consider smoothed polynomial transforms, such as those arising from local estimates of angular power spectra and bispectra; we focus on the geometry of their excursion sets, and we study their asymptotic behaviour, in the high-frequency sense. Our main technical tools are recent results on Malliavin calculus and Total Variation bounds for Gaussian subordinated fields by Nourdin and Peccati, and the Gaussian Kinematic Formula by Adler and Taylor, which we shall review briefly in the talk. We put particular emphasis on the analysis of Euler-Poincaré characteristics, which can be exploited to derive extremely accurate estimates for excursion probabilities. The present analysis is motivated by the statistical investigation of asymmetries and anisotropies in Cosmic Microwave Background radiation (CMB) data. Based on joint work with Sreekar Vadlamani Part II: Stein-Malliavin Approximations for Needlets Polyspectra Valentina Cammarota We provide quantitative Central Limit Theorems, in the high frequency limit, for nonlinear transforms of spherical wavelets/needlets random fields, which are of immediate interest for spherical data analysis. In particular, we focus on so-called needlets polyspectra, which are popular tools for nonGaussianity analysis in the cosmological community, and on the area of excursion sets. Our results are based on Stein-Maliavin approximations for nonlinear transforms of Gaussian fields, and on an explicit derivation on the high-frequency limit of the fields' variances, which may have some independent interest. Based on joint work with Domenico Marinucci Part III: Normal Approximations for Linear and U-Statistics on Spherical Poisson Fields Claudio Durastanti We review a recent stream of research on Normal approximations for linear and U-statistics of wavelets/needlets coefficients evaluated on a homogeneous spherical Poisson fi...eld. We show how exploting results from Peccati and Zheng (2011), based on Malliavin calculus and Stein''s methods, it is possible to assess the rate of convergence to Gaussianity for a triangular array of statistics with growing dimensions. These results can be exploited in a number of statistical applications, such as spherical density estimations, searching for point sources, estimation of variance and the spherical two-sample problem. Based on joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati.

Seminario di Guido Montorsi (Roma - 11 aprile)
by Marco Isopi 29 Mar '14

29 Mar '14

Seminari MoMA www.mat.uniroma1.it/ricerca/seminari/moma Venerdi’ 11 aprile, ore 12-14, aula Consiglio Guido Montorsi Analog Digital Belief Propagation and its application to channel decoders Sunto As required by information theory, channel codes with long code words are necessary building blocks in a transmission system to achieve reliable communications with minimal power and maximal throughputs over noisy physical channels. Nowadays capacity-achieving large random binary codes are actually adopted in most telecommunication standards. The breakthrough that allowed their practical use has been to substitute the optimal maximum likelihood decoding techniques at the receiver with suboptimal iterative techniques based on “belief” propagation. Belief propagation is a powerful inference technique working on graphs used in many different applications. Graph nodes are associated to factors or constraints of the model while graph edges are associated to random variables. Belief propagation algorithm proceeds by iteratively updating messages associated to the random variables, according to the constraints imposed by nodes. In the framework of channel decoding the graph nodes represent the deterministic, usually linear, code constraints. They are either associated to a (binary) parity check sum, or to a repetition of the variable. Belief propagation is initialized with a set of messages obtained from the noisy channel observations of the transmitted bits and proceeds iteratively, updating the messages according to the code constraints until convergence is reached. Most practically used codes are linear and binary codes, so that messages propagated in the graph are binary messages usually represented with a single scalar (the Log-Likelihood Ratio). In order to increase the throughput of communication systems, the use of non binary codes is an attractive solution as each symbol can carry more information bits. Non binary codes can be constructed over groups, rings, or fields and there is a vast literature on the design of capacity achieving non binary codes. The extension of the application of belief propagation to the non binary codes however poses several complexity problems as both message representation and message updating at check node grows at least linearly with the cardinality of the non binary alphabet and consequently exponentially with the increase of required throughput. In this talk I will start by recalling the fundamental ideas and terminology beyond binary channel coding constructions and corresponding iterative decoding with belief propagation and other iterative techniques. I will then extend the concepts to non binary codes and summarize the main algorithms and complexity problems related with them. I will then introduce a new algorithm, named Analog Digital Belief Propagation (ADBP) which solves the complexity problems of belief propagation for non binary codes. I will discuss the main properties of the algorithm, its possible extensions and code design problems related to the adoption of this algorithm.

Asachi" Technical University, Romania terrà un seminario dal titolo Stochastic Differential Delay Systems and Optimal Control Problems *Abstract* We show the existence and the uniqueness of the solution for some multivalued stochastic differential equation with delay (the multivalued term is of subdifferential type). Afterwards we consider optimal control problems where the state X is a solution of a controlled delay stochastic system as above. We establish the dynamic programming principle for the value function and finally we prove that the value function is a viscosity solution for a suitable Hamilton- Jacobi-Bellman type equation. __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.

Il giorno Giovedì 3 Aprile 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Daniele MARAZZINA (Politecnico di Milano) terrà un seminario dal titolo "Fast pricing of discretely monitored exotic options by a numerical Wiener-Hopf procedure" Abstract We present a fast and accurate pricing techniques based on the Spitzer identity and the Wiener-Hopf factorization. We apply it to barrier and lookback options when the monitoring is discrete and the underlying evolves according to an exponential Lévy process. The numerical implementation exploits the fast Fourier transform and the Euler summation. The computational cost is independent of the number of monitoring dates; the error decays exponentially with the number of grid points.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 4 Aprile 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Judith ROUSSEAU (Université Paris Dauphine) BEHAVIOUR OF THE POSTERIOR DISTRIBUTION IN HMM MODELS WHEN THE NUMBER OF STATES IS MISSPECIFIED Abstract: In this paper we study the asymptotic behaviour of the posterior distribution for parametric HMM models with finite number of components. We concentrate in particular on the case where the number of states of the hidden Markov chain in the model is larger than the true number of states. In such cases the parameter is not identifiable. We study the impact of the prior on the transition matrix on the asymptotic behaviour of the posterior distribution. In particular that if some independent Dirichlet priors are considered on each row of the transition matrix we can identify different types of behaviour of the asymptotic posterior distribution depending on the choice of the parameter of the Dirichlet distributions. A link is made with static mixture models and some numerical study is conducted to illustrate the results and investigate the behaviour of the posterior in cases where no theoretical results are provided. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

seminario di Pablo Ferrari a Roma Tre
by pietro caputo 28 Mar '14

28 Mar '14

Martedi 1 Aprile, alle ore 14:30 in aula 311 del Dipartimento di Matematica e Fisica dell'Universita' di Roma Tre, il Prof. Pablo Ferrari (Buenos Aires) terra' un seminario su: "Yaglom limits via Holley inequality" Abstract: We consider Markov chains on a countable partially ordered state space with an absorbing state. Assume that the absorbed chain has a quasi stationary distribution. We give sufficient conditions on the transition probabilities to guarantee that the law of the chain at time n conditioned to non absorption is monotone non decreasing in n. As a consequence the Yaglom limit (the limit of the conditioned chain starting from a minimal state, as n goes to infinity) converges to a quasi stationary distribution; the limit is minimal for the stochastic order of measues. The approach uses a dynamics on the space of trajectories and Holley inequality. Joint work with Leonardo Rolla.

Due to the lack of uniform ergodicity, the zero level set of the rate function is not a singleton. As a corollary, we deduce the Donsker-Varadhan large deviation principle for the empirical measure. We discuss in detail an example given by a linear phonon Boltzmann equation.

de Finetti risk seminar - marzo 2014
by Emanuela Rosazza Gianin 12 Mar '14

12 Mar '14

On behalf of the Scientific Committee of The de Finetti Risk Seminars - on the Mathematical Theory of Economics and Finance in Milano, we are glad to invite you to participate at the "de Finetti Risk Seminar" on March 19, 2014 at 18.00 with the Lecture A continuous auction model with insiders GIULIA DI NUNNO University of Oslo ABSTRACT In a unified framework we study equilibrium in the presence of an insider having information on the signal of a firm value, which is naturally connected to the fundamental price of the firm related asset. The fundamental value itself is announced at some future random stopping time. We consider the two cases in which this release time of information is known and not known to the insider. We study the structure of the optimal insider's strategies in equilibrium and we discuss market efficiency in the two cases of insider's information. Some examples of explicit insider's strategy will be provided. This is joint work with Jose Manuel Corcuera, Gergely Farkas, and Bernt Øksendal. LOCATION: The seminar will be held on Wedsnesday, March 19, at 18.00 at Aula Chisini, Department of Mathematics, Milano University, Via Saldini 50, Milano. A refreshment will be offered at 17.30.

Il giorno Giovedi 13 Marzo alle ore 16 presso il GSSI (Gran Sasso Science Institute, L'Aquila) la Prof. *Inés Armendariz *del Dipartimento di Matematica dell'Università di Buenos Airesterrà il seguente seminario: *Title*: Scaling limit of the condensate dynamics in the zero-range process *Abstract*: We consider the zero-range process on the one dimensional torus with L sites and N particles, in the supercritical regime when N=L exceeds the critical density. It is known that in the stationary state, as L goes to infinity, the excess particles accumulate at a randomly chosen position, forming the condensate. We now show that, at the right scale, this condensates moves according to a Lévy process on the rescaled torus, with rates determined by the jump distribution of the original zero range process. For instance, for nearest neighbour probabilities, the limiting Lévy process will have rates inversely proportional to the jump length. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Two seminars and presentation of Ph.D. theses - date
by Tiziano Vargiolu 03 Mar '14

03 Mar '14

We have the pleasure to announce the following two seminars and the defenses of two PhD thesis for the day Friday, March 7th: University of Padova, Italy Department of Mathematics, via Trieste 63 room 1BC/45, 1st floor 9.00 Tomas BJORK: "Time inconsistent control" (joint with Agatha Murgoci) ABSTRACT: We develop a theory for stochastic control problems which, in various ways, are time inconsistent in the sense that they do not admit a Bellman optimality principle. We attach these problems by viewing them within a game theoretic framework, and we look for Nash subgame perfect equilibrium points. For a general controlled Markov process and a fairly general objective functional we derive an extension of the standard Hamilton-Jacobi-Bellman equation, in the form of a system of non-linear equations, for the determination for the equilibrium strategy as well as the equilibrium value function. Most known examples of time inconsistency in the literature are easily seen to be special cases of the present theory. We also prove that for every time inconsistent problem, there exists an associated time consistent problem such that the optimal control and the optimal value function for the consistent problem coincides with the equilibrium control and value function respectively for the time inconsistent problem. We also study some concrete examples. 10.00 Thorsten SCHMIDT: "Bond markets and absence of arbitrage beyond the existence of a bank account" (joint with Irene Klein and Josef Teichmann) ABSTRACT: We investigate default-free bond markets where the standard relationship between a possibly existing bank account process and the term structure of bond prices is broken, i.e. the bank account process is not a valid numeraire. We argue that this feature is not the exception but rather the rule in bond markets when starting with, e.g., terminal bonds as numeraires. Our setting are general cad lag processes as bond prices, where we employ directly methods from large financial markets. Moreover, we do not restrict price process to be semimartingales, which allows for example to consider markets driven by fractional Brownian motion. In the core of the article we relate the appropriate no arbitrage assumptions (NAFL), i.e. no asymptotic free lunch, to the existence of an equivalent local martingale measure with respect to the terminal bond as numeraire, and no arbitrage opportunities of the first kind (NAA1) to the existence of a supermartingale deflator, respectively. In all settings we obtain existence of a generalized bank account as a limit of convex combinations of roll-over bonds. Additionally we provide an alternative definition of the concept of a numeraire, leading to a possibly interesting connection to bubbles. If we can construct a bank account process through roll-overs, we can relate the impossibility of taking the bank account as numeraire to liquidity effects. Here we enter endogenously the arena of multiple yield curves. After the two seminars, the defenses of two PhD thesis will take place: 11.00 Juan Miguel MONTES: "Aspects of affine models in the pricing of exotic options and in credit risk" (supervisor: Wolfgang J. Runggaldier) 11.45 Stefano PAGLIARANI: "Portfolio optimization and option pricing under defaultable Levy driven models" (supervisor: Tiziano Vargiolu) Tiziano -------------------------------------------------------------------------- Tiziano Vargiolu Dipartimento di Matematica Phone: +39 049 8271383 Universita' di Padova Fax: +39 049 8271428 Via Trieste, 63 E-mail: vargiolu(a)math.unipd.it I-35121 Padova (Italy) WWW: http://www.math.unipd.it/~vargiolu --------------------------------------------------------------------------

This international conference - in short *ICFIS2014* <http://icfis2014.org/> - unites lawyers, statisticians and forensic scientists in their interest in optimal reasoning concerning forensic evidence. Technical developments in biological, physical, chemical and digital forensic disciplines are fast and have an increasing impact on law enforcement and the justice system. Examples are DNA profiling, fingerprint and illicit drug analysis, and analysis of large digital data-sets for intelligence purposes. Whatever the type of evidence, it can only be of value when it is properly gathered, analyzed, evaluated, and communicated by the scientist. Moreover, it should be understood by the legal decision maker. This requires sound statistical and logical methods, and good communication between lawyers and scientists. The conference promotes the interaction between providers and users of forensic evidence. It focuses on probabilistic methods for the evaluation of forensic evidence, and their use in law and law enforcement. The conference will provide a forum for oral presentations and posters. Furthermore, the first day of the conference will consist of workshops. Selection by the scientific committee of the contributions for the final program is based on abstracts. If you haven't done so already, please submit your abstract by digitally filling out the form you can download from the website <http://dl.dropboxusercontent.com/u/6795661/ICFIS2014/abstracts.html>, and sending it to abstracts(a)icfis2014.org <mailto:abstracts@icfis2014.org>. *The final deadline for abstract submission is March 13, 2014. * The website lists the themes <http://dl.dropboxusercontent.com/u/6795661/ICFIS2014/index.html#themes> for the conference. See you at ICFIS2014!

Buongiorno, Martedi' 4 marzo Claudio Landim terra' un seminario al Dipartimento di Matematica (Sapienza, Roma). sotto trovate i dettagli. cordiali saluti alessandra faggionato Martedi' 4 Marzo, Aula C (Dip. Matematica, Univ. Sapienza), ore 14:30 Speaker: C. Landim (IMPA Rio De Janeiro, CNRS Rouen) Title: Zero-temperature limit of the Kawasaki dynamics for the Ising lattice gas in a large two-dimensional torus Abstract: We consider the Kawasaki dynamics at inverse temperature $\beta$ for the Ising lattice gas on a two-dimensional square of length $2L+1$ with periodic boundary conditions. We assume that initially the particles form a square of length $n$, which may increase, as well as $L$, with $\beta$. We show that in a proper time scale $L^2\, \theta_\beta$ particles form almost always a square and that this square evolves as a Brownian motion when the temperature vanishes. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A.

Colloquium Fabio Lucio Toninelli a Roma Tre
by pietro caputo 21 Feb '14

21 Feb '14

Mercoledi' 26 febbraio 2014 Ore 16:00, Aula F Dip. Matematica e Fisica Roma Tre EDIFICIO AULE LARGO SAN L. MURIALDO,1 Colloquium di Matematica Fabio Toninelli (Universita' di Lione) Random tilings, Glauber dynamics and macroscopic shapes I "piastrellamenti" (tiling) del piano sono un oggetto classico in meccanica statistica e combinatoria. Se le "piastrelle" sono a forma di losanga, si ha una corrispondenza esatta con le interfacce del modello di Ising 3-dimensionale a temperatura nulla. A ogni piastrellamento e' possibile associare una funzione di altezza (superficie discreta). E' ben noto [Cohn-Kenyon-Propp] che, se la taglia della regione U da piastrellare tende all'infinito, la funzione altezza associata a un piastrellamento scelto uniformemente tende verso una certa forma limite macroscopica che risolve una PDE ellittica non-lineare. Sull'insieme dei piastrellamenti si puo' definire una dinamica stocastica che corrisponde alla dinamica di Glauber a temperatura zero per il modello di Ising. Un problema classico e' quello di stimare il tempo (mixing time) che la dinamica richiede per raggiungere l'equilibrio (la misura uniforme). La congettura, basata sull'idea euristica che l'interfaccia evolve seguendo un'equazione di tipo "movimento per curvatura media", e' che il mixing time cresca essenzialmente come il quadrato del diametro della regione U. Il nostro risultato principale e' una prova di questa congettura, sotto l'ipotesi che la forma macroscopica non presenti singolarita'. Basato su lavori in collaborazione con P. Caputo, B. Laslier e F. Martinelli.

We present a statistical model for the quantitative peak information obtained from an electropherogram (EPG) of a forensic DNA sample and illustrate its potential use for the analysis of criminal cases. In contrast to most previously used methods, we directly model the peak height information and incorporates important artefacts associated with the production of the EPG. Our model has a number of unknown parameters, and we show that these can be estimated by the method of maximum likelihood in the presence of multiple unknown contributors, and their approximate standard errors calculated; the computations exploit a Bayesian network representation of the model. A case example from a UK trial, as reported in the literature, is used to illustrate the efficacy and use of the model, both in finding likelihood ratios to quantify the strength of evidence, and in the deconvolution of mixtures for the purpose of finding likely profiles of one or more unknown contributors to a DNA sample. Our model is readily extended to simultaneous analysis of more than one mixture as illustrated in a case example. We show that combination of evidence from several samples may give an evidential strength close to that of a single source trace and thus modelling of peak height information provides for a potentially very efficient mixture analysis.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 21 Febbraio 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Nicolas CHOPIN (ENSAE, France) SEQUENTIAL QUASI MONTE CARLO Abstract: We develop a new class of algorithms, SQMC (Sequential Quasi Monte Carlo), as a variant of SMC (Sequential Monte Carlo) based on low-discrepancy points. The complexity of SQMC is O(N log N) where N is the number of simulations at each iteration, and its error rate is smaller than the Monte Carlo rate O(N^{-1/2}). The only requirement to implement SQMC is the ability to write the simulation of particle x_t^n given x_{t-1}^n as a deterministic function of x_{t-1}^n and uniform variates. We show that SQMC is amenable to the same extensions as standard SMC, such as forward smoothing, backward smoothing, unbiased likelihood evaluation, and so on. In particular, SQMC may replace SMC within a PMCMC (particle Markov chain Monte Carlo) algorithm. We establish several convergence results. We provide numerical evidence in several difficult scenarios than SQMC significantly outperforms SMC in terms of approximation error. Joint work with Mathieu Gerber. Tutti gli interessati sono invitati a partecipare.

An important feature of the quasi-taper is given by a spatial (temporal) compact support being a decreasing function of the temporal lag (spatial distance), so that the spatial (temporal) compact support becomes smaller when the temporal (spatial) dependence becomes weaker. We propose general classes as well as some examples that generalize the Wendland tapers to the space-time setting. Then a non separable space-time taper with spatial and temporal compact support is obtained as tensor product of quasi-tapers. Our space-time taper includes all the known constructions as special cases and will be shown to have great exibility. Covariance tapering is then explored as an alternative to maximum likelihood when estimating the covariance model of a space-time Gaussian random field in the case of large datasets. The proposed quasi and space-time tapers allows to perform covariance tapering when dealing with data that are densely observed in time (space) but sparse in space (time) or densely observed both in time and space. The statistical and computational properties of the space-time covariance tapering is addressed under increasing domain asymptotics. A simulation study and two real data examples illustrate the statistical and computational performances of the covariance tapering with respect to the maximum likelihood method using the space-time tapers proposed.

Seminario di Giovanni Puccetti presso Prometeia - Bologna
by Giacomo Scandolo 10 Feb '14

10 Feb '14

Il giorno Giovedì 13 Febbraio 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Giovanni PUCCETTI (Università di Firenze) terrà un seminario su: RISK AGGREGATION AND MODEL UNCERTAINTY: SOME MESSAGES FROM THE METHODOLOGICAL FRONT Abstract. We review some of the most recent mathematical achievements in the field of Risk Aggregation and Model Uncertainty and discuss their implications on the current Basel regulatory framework, with particular emphasis on VaR/ES risk measurement. Specific issues that will be handled: - How much superadditive can VaR be? - What are the likely constraints with moving from VaR to ES? - Which kind of dependence is implied by a worst-VaR scenario? - What are the available tools to capture the model uncertainty associated with a joint risk position?

Il 19 febbario alle ore 14:30 presso l'aula seminari (III piano) Dipartimento di Economia, Universit? Roma Tre, Via Silvio D'Amico 77 il Prof. Stefano Iacus Dipartimento di Economia, Management e Metodi Quantitativi Universit? degli Studi di Milano terr? il seminario: ***Statistics over Big Data: How to Analyze 80 Millions of Tweets*** Abstract: There are several ways to analyze data coming from digitized texts and there are even more ways to analysis big amount of these data. Analyzing the sentiment expressed on social networks is both about big data and digitized text. But sentiment analysis is not just text mining, i.e. usual data mining applied to text data, because what matters is to capture the meaning of sentences in a corpora of texts whose language evolves in time and space or according to the age, the background of the writers, etc. We will discuss the most recent techniques of sentiment analysis available in the literature along with some new ideas and present some applications to the analysis of 80 millions of italian tweets to happyness and economics.

seminari di O. Aryasova e E. Orsingher a Pisa
by Marco Romito 04 Feb '14

04 Feb '14

Il giorno 11 febbraio 2014, presso l'aula seminari del Dipartimento di Matematica dell'Università di Pisa, si terranno i seguenti seminari: 10:30 Olga Aryasova (Institute of Geophysics, National Academy of Sciences of Ukraine): A representation for the derivative with respect to the initial data of the solution of an SDE with non-regular drift 11:30 E. Orsingher (Roma Sapienza): Random flights Tutti gli interessati sono invitati a partecipare. m. _______________________________________________ abstract Aryasova We consider a multidimensional SDE with an identity diffusion matrix and a drift vector being a bounded measurable vector field. According to [Ver81] there exists a unique strong solution to such an equation. Recently the Sobolev differentiability of the solution with respect to the initial data was proved under rather weak assumptions on the drift (c.f. [Fed13,Moh12]). If the drift coefficient is smooth the derivative can be represent as a solution of an integral equation. For non-regular drift in dimension one such a representation was obtained using the local time of the initial process (see [Ary12,Att10]). It is well known that the solution does not have a local time at a point in multidimensional situation. We obtained the representation of the derivative using the theory of continuous additive functionals developed by Dynkin [Dyn63]. This method can be considered as a generalization of the local time approach to the multidimensional case. [Ary12] O. V. Aryasova and A. Yu.

USSR Sborn, 39(3):387--403, 1981. _______________________________________________ abstract Orsingher In this talk we present different types of random flights and examine their dynamics, probability laws and governing equations. We first consider the telegraph process (a random flight on the line), discuss its distribution, the connections with the telegraph equations, the first-passage time and the limiting case. We consider also the asymmetric telegraph process and its reduction to the symmetric one by means of relativistic transformations. Planar motions with a finite number of directions (in particular, four orthogonal directions) and an infinite number of directions, chosen at Poisson times with uniform law, are examined and several explicit distributions derived. A particular attention is devoted to the second model, where conditional and unconditional distributions are presented and the related equation of damped planar vibrations probabilistically derived. Random flights in R^d are subsequently considered and characteristic functions of the position of moving particles performing the random flights, obtained. The cases d = 2, d = 4, are investigated in detail. We present random flights in R^d with Dirichlet joint distribution for displacements, hyper-spherical uniform law for the orientation of steps and with a fractional Poisson number of changes of direction. Two types of fractional extensions of the above material are presented. The first one is obtained by considering Dzerbayshan-Caputo types of time- fractional derivatives. The second fractional extension is obtained by considering fractionalisation of Klein-Gordon equations and by applying the McBride approach to fractional powers of Bessel-type operators.

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, il Dott. ROBERT KNOBLOCH (Department of Mathematics -- Saarland University) terrà un seminario dal titolo "An Itō type formula and related properties for convoluted Lévy processes" Abstract: In this talk we derive moment and path properties as well as an Itō type formula for a large class of convoluted Lévy processes M(t) that in particular contains fractional Lévy processes. To this end we make use of the S-transform, which is defined as the expectation under a suitable change of measure and results in Hitsuda-Skorokhod integrals appearing in our main results. For the general version of our Itō type formula we assume that the underlying Lévy process has a nontrivial Gaussian component and use this assumption to prove that the characteristic function of M(t), under the aforementioned changed measure, has nice integrability properties. This enables us to weaken the conditions in the Itō type formula compared to related results in the literature. Tutti gli interessati sono invitati a partecipare.

Seminario di Probabilità a Roma Tre Alexandre Stauffer (University of Bath) Titolo: Mixing time of random walks on dynamical percolation Martedi' 04 Febbraio 2014 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 211 Largo San L. Murialdo,1 Abstract We study the behavior of random walk on dynamical percolation. In this model, the edges of a graph G are either open or closed and refresh their status at rate mu while at the same time a random walker moves on G at rate 1 but only along edges which are open. On the d-dimensional torus with side length n, we prove that in the subcritical regime, the mixing times is of order n^2/mu. We also obtain results concerning mean squared displacement and hitting times.This is a joint work with Yuval Peres and Jeff Steif.

Giovedì 6 febbraio, alle ore 15:00, presso l'aula Seminario VII del Dipartimento di Matematica di Padova la Prof.ssa Irene Crimaldi (IMT Lucca) terra' il seguente seminario TITLE: Asymptotic Results for some Preferential Attachment Models with Random Weights ABSTRACT: Various asymptotic results will be shown for the "randomly reinforced" versions of three popular models: Polya urn, Poisson-Dirichlet sequence and Indian buffet process. The main central limit theorem will be stated for an arbitrary sequence of real random variables. Indeed, although this result has been thought for urn problems, it deals with the general problem of the rate of convergence of predictive distributions and empirical distributions for dependent data.

Seminario di Fabio Gobbi a Bologna
by giacomo.scandolo＠univr.it 27 Jan '14

27 Jan '14

Il giorno Giovedì 30 Gennaio 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna si terrà il Seminario del Dott. Fabio Gobbi Dipartimento di Scienze Statistiche, Università di Bologna Titolo: C-CONVOLUTION AND ITS APPLICATION TO FINANCE Abstract In ﬁnancial applications is interesting to determine the distribution function of the sum of two random variables X and Y in the case where they are dependent. We address the problem using the convolution operator which recovers the distribution of X+Y when a copula function C describes the dependence structure and the marginal distributions of the two r.vs. are given. Nevertheless, almost all the ﬁnancial data are generated by stochastic processes. Our C-convolution approach allows to build dependent increments processes since setting X = X(t-1) − and Y = DX, their sum is X_t . In this framework we model the dependence structure between the level of the process and its next increment. From an empirical point of view, ﬁnancial data are time series and the econometric analysis is provided by the concept of conditional copula introduced by Patton (2006) which allows us to deﬁne the conditional 𝐶-convolution as a data generating process. We estimate such a model by a three-stage maximum likelihood method and we provide some asymptotic results of this estimator. An immediate ﬁnancial application of such a method is given by a copula-based model to recover the distribution of actively managed funds. The analysis is based on a general representation of the Henriksson Merton (1981) model, in which the forecasting ability of the asset manager is modeled with a copula function (linking the forecasts of the asset manager and actual market movements). This is a convolution-based copula yielding at the same time the marginal distribution of the return on the managed fund and the dependence structure between the managed fund and the market. The model is very well suited to estimate and simulate the conditional distribution of managed funds.

In order to take into proper account such difficulties, it is possible to consider surrogates of the original likelihood, which produce the wide class of the so-called pseudo-likelihoods. In this talk we review the properties and applications of the so-called pseudo-posterior distributions, i.e. posterior distributions derived from the combination of a pseudo-likelihood function with suitable prior information. Some examples are illustrated.

In the basic LM, a random intercept is flexibly allowed to evolve over time. The available formulations of mixed LM often assume that any additional random effect is time-constant, with few specific exceptions. In this work we formulate a mixed latent Markov model in which all random effects may freely evolve over time. The size of the parameter space is controlled with the possibilities of assuming block independence of random effects, and/or that groups of random effects may share some or all aspects of their distribution. Parameter estimation is carried out with a simple expectation maximization strategy, analogous to that used for the basic latent Markov model, after an adaptation of the usual forward backward recursions and a parsimonious representation of the expected complete likelihood. Standard errors are derived using Oakes' identity. Dependence among random effects is summarized using Watanabe's total correlation and described with log-odds ratios and higher-order log-linear interactions. We illustrate with an original application to the relationship between health literacy and depression in a panel of adolescents. In this example subjects are clustered in schools, which leads to high-dimensional multivariate time-varying random effects.

The geometric invariants are the fixed length of a random chain and the constant radius of a sphere, which is the surface for random walks (for example, in the case of a turning diffusion). The integral invariants are represented as integrals of kernel functions of integral invariants on the whole space. These kernel functions are solutions of SDEs, which were obtained and discussed. Furthermore, kernel functions will be used for deriving the first global stochastic integral, for constructing the program control (with probability one) for stochastic dynamical systems on deterministic manifold based on Brownian motion with Poisson jumps, and for obtaining the Kolmogorov equations.

Cari colleghi, vi ricordiamo che il prof. Ivan Gentil (Université Lyon 1) terrà, presso il Dipartimento di Matematica dell'Università di Pavia, un mini-corso dal titolo The Bakry-Emery condition applied to the functional inequality and contraction in Wasserstein distance Abstract : During the lessons we would like to introduce the Bakry-Emery condition in the Euclidean space R^n and also in a Riemannian manifold. First we study the two classical examples: the Euclidean Heat semigroup and the Ornstein-Uhlenbeck semigroup. Then we define the general setting: a Markov semigroup associated to the Gamma and the Gamma-2 operators. Under the Bakry-Emery condition we obtain coercive inequalities which implies for instance functional inequality such as Poincaré or logarithmic-Sobolev inequalities. The last part of the course is devoted to the contraction in wasserstein distance under the Bakry-Emery condition. Orario (provvisorio): ore 11-13 nei giorni 14, 15, 17, 20, 22, 24 gennaio 2014.

de Finetti Risk seminar - gennaio 2014
by Emanuela Rosazza Gianin 08 Jan '14

08 Jan '14

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture PREFERENCE TO DIVERSIFICATION: DIFFERENT BUT INTRICATE DIMENSIONS OF UNCERTAINTY AVERSION Samuel Drapeau ABSTRACT We study the preferences of agents for diversification and better outcomes when they are facing both, in Frank Knight's formulation, measurable as well as unmeasurable uncertainty. Following Anscombe and Aumann, such a situation can be modeled by preferences expressed on stochastic kernels, that is scenario dependent lotteries. By means of automatic continuity methods based on Banach-Dieudonné's Theorem on Fréchet spaces, we provide a robust representation. This gives us some insight into the nature of uncertainty aversion these preferences are expressing. We further investigate under which conditions these two intricate dimensions of uncertainty can be disentangle into a distributional uncertainty, in the direction of von Neumann and Morgenstern's theory, and a probability model uncertainty, in the spirit of risk measures. These results allow in particular to address both Allais as well as Elsberg's paradox. LOCATION: The seminar will be held on Wednesday, 15 January, at 18.00 at Aula di Rappresentanza, Department of Mathematics, Milano University, Via Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

Seminario Prof.ssa Youngna Choi @ SNS Pisa
by Giacomo BORMETTI 07 Jan '14

07 Jan '14

Buongiorno a tutti, vi segnalo il seminario della Prof.ssa Youngna Choi della Montclair State University che si terrà a Pisa presso la Scuola Normale Superiore il prossimo 9 Gennaio alle ore 13:00 in Aula Bianchi. Seguono titolo e abstract. Titolo: Financial Instability Contagion: a Dynamical Systems Approach Abstract: We build a multi-agent dynamical system for the global economy to investigate and analyze financial crises. The agents are large aggregates of a subeconomy, and the global economy is a collection of subeconomies. We use well-known theories of dynamical systems to represent a financial crisis as propagation of a negative shock on wealth due the breakage of a financial equilibrium. We first extend the framework of the market instability indicator, an early warning signal defined for a single economy as the spectral radius of the Jacobian matrix of the wealth dynamical system. Then, we formulate a quantitative definition of instability contagion in terms thereof. Finally, we analyze the mechanism of instability contagion for both single and multiple economies. Our contribution is to provide a methodology to quantify and monitor the level of instability in sectors and stages of a structured global economic model and how it may propagate between its components. Tutti gli interessati sono cordialmente invitati.

Thank you very much! Best wishes, Juri ------------------------------- Associate Professor Juri Hinz University of Technology Sydney PO Box 123, Broadway NSW 2007 Australia Phone: 9514 2252 Room: CB01.1550 Fax: +61 2 95142260 Email: juri.hinz(a)uts.edu.au ______________________________ Mathematical modelling in mining industry The UTS School of Mathematical Sciences and CSIRO Computational Informatics are seeking a PhD student to undertake research on optimisation in planning and management of minerals extraction and processing under uncertainty. The successful applicant will be awarded a highly competitive $30,000 per annum scholarship plus access to the unique doctoral training program under the auspices of the Industry Doctoral Training Centre in Mathematics and Statistics (visit http://www.gradschool.uts.edu.au/atn/ for more information). Australia has the world?s largest reserves of mineral sands, brown coal, nickel, lead, silver, uranium, iron ore, zinc and other minerals. Australia is ideally positioned within Asia?Pacific, the fastest growing region in the world. Unprecedented demand for commodities from the region has driven high levels of investment in minerals exploration and project developments. Australia?s abundant mineral resources, advanced mining equipment, technology and services industry, and proximity to the rapidly growing markets, have made it a world leading mining nation. The challenges of modern mining industry include a need for sophisticated technologies to extract minerals from low?grade ores, managing labour cost and increasingly focus on environmental sustainability. The costs associated with processing technologies must account for high level of uncertainty resulting from market conditions and ore quality. These risk factors have a significant impact on the profitability of mining projects, whose optimization focuses on correct choice of both, the operating policy and long?term strategic decisions. In this framework, optimising investments and decision?making are challenging and interesting stochastic control problems. This project focuses on mathematical models and efficient methods for numerical treatment of control problems arising in the decision?making process in the minerals industry. On practical side, these models and methods are of crucial importance for individual policy optimization. On the theoretical side, this research offers a unique opportunity to break in into a highly interesting, versatile and active area of modern mathematics, where practical questions challenge cutting?edge theoretical approaches. Being placed between real option theory, quantitative risk management, and Markov decision theory, the potential impact of this work is substantial and can position the student extremely well, beyond the award of a PhD degree. The quantitative known?how in these field provides an ideal starting point for both a future work in the financial industry, consultancies, minerals business and/or a career in academia. This PhD research project is a collaborative arrangement between UTS and CSIRO and will be supervised by A/Professor Juri Hinz (UTS) and Dr Tanya Tarnopolskaya (CSIRO). Selection Criteria 1. First class honours or equivalent in mathematics or other relevant discipline. 2. Demonstrated academic ability in statistics, stochastic processes and model implementation. 3. Sound knowledge of computer languages, at least one from C++, R, Mat lab, Python, Java How to apply Please send an email to both supervisors: Juri.Hinz(a)uts.edu.au Tanya.Tarnopolskaya(a)csiro.au ------------------------------- UTS CRICOS Provider Code: 00099F DISCLAIMER: This email message and any accompanying attachments may contain confidential information.

mini corso prof. Ivan Gentil a Pavia
by Carbone Raffaella 19 Dec '13

19 Dec '13

Cari colleghi, vi annunciamo che il prof. Ivan Gentil (Université Lyon 1) terrà, presso il Dipartimento di Matematica dell'Università di Pavia un mini-corso dal titolo The Bakry-Emery condition applied to the functional inequality and contraction in Wasserstein distance Abstract : During the lessons we would like to introduce the Bakry-Emery condition in the Euclidean space R^n and also in a Riemannian manifold. First we study the two classical examples: the Euclidean Heat semigroup and the Ornstein-Uhlenbeck semigroup. Then we define the general setting: a Markov semigroup associated to the Gamma and the Gamma-2 operators. Under the Bakry-Emery condition we obtain coercive inequalities which implies for instance functional inequality such as Poincaré or logarithmic-Sobolev inequalities. The last part of the course is devoted to the contraction in wasserstein distance under the Bakry-Emery condition. Orario (provvisorio): ore 11-13 nei giorni 14, 15, 17, 20, 22, 24 gennaio 2014. -- Raffaella Carbone, PhD Ricercatore di Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Biometrical Journal, Special Issue on "Models for continuous data with a spike at zero"
by Pierpaolo Brutti 16 Dec '13

16 Dec '13

...ricevo e inoltro... ### APOLOGIES FOR CROSS_POSTING #### The Biometrical Journal is a leading journal in biometry. It is calling for papers for a special issue on "Models for continuous data with a spike at zero". Zero-inflation models for count data have a long history and a huge amount of published research exists to the topic. In fact, the Biometrical Journal has contributed numerous papers to this area since zero-inflated count data are a prominent problem in the life-sciences. See, for example, the September 2013 issue of the Biometrical Journal. In this call, we would like to draw the attention of the research community to another prominent problem in the life sciences: continuous data with a spike at zero. The extra-zeros can arise out of many reasons and it is not necessarily clear how they could be handled. A frequent problem is the occurrence of data below a limit of detection (LOD). In these cases, it might be reasonable to treat them as left-censored. A further modeling alternative could be that of employing so called two-step models, where at the first stage a binary variable describes whether or not the observed value is above the limit of detection while, at the second stage, a continuous variable is used to describe positive measurements. In other cases, it is less clear how to approach the problem. For example, consider the consumption of alcohol measured on a continuous scale. Then, there is a spike at zero representing the non-drinkers. The zeros are neither left-censored nor interval-censored. Here, there are at least two problems involved. For one, the quantity of interest is bounded below, and for two, the zeros create a single mass distribution. A further empirical application where extra-zeros may arise is when modeling length of stay in hospital admissions. This is frequently modeled following a count data approach, although the underlying quantity is continuous. In length-of-stay situations, day surgery patients may be classified as having a null length of stay but, for administrative purposes, it could be necessary for them to be considered together with in-hospital patients whose length of stay is positive. Hence, we have a continuous quantity bounded below by zero and a spike at zero. In a regression context, we also think that these spikes could occur on the left-hand side of a regression equation as well as on the right-hand side, i.e. for the dependent (outcome) and the independent (predictor) variables With this call for submissions we are looking for novel contributions presenting • authentic continuous data with excess-zeros • novel statistical approaches to handle these issues. • up-to-date case studies which address the above issues and are of interest for the biometric community. . Authors, who are not sure whether their problems and ideas fall under the call or not, may approach the Editors with an initial draft of the paper. All submitted papers under this call will undergo the standard review process of the journal. The deadline for papers for this call is May 31, 2014. The special issue is handled through the website of the Biometrical Journal and is handled as any other paper submitted to the journal except that the editing and the review process is handled by the Special Issue Editors Dankmar Böhning and Marco Alfó. Please submit your manuscript at is http://mc.manuscriptcentral.com/biomj To submit to the special issue login at MC (manuscript central), indicate at Step 1 that the submission is to a special issue and at Step 4 of the submission process enter "ZERO I" in the Special Issue Information field. Submitted manuscripts should comply with the instructions for authors of Biometrical Journal which you find on the Biometrical Journal homepage using the link to the Author Guidelines.

**************************************************************** STATISTICS SEMINARS - COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 20 dicembre 2013 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Bas KLEIJN (University of Amsterdam) TESTABILITY AND CONSISTENCY Abstract: Bayesian consistency theorems come in (at least) three distinct types, e.g. Doob's prior-almost-sure consistency on Polish spaces, Schwartz's Hellinger consistency with KL-priors and the `tailfree' weak consistency of Dirichlet posteriors. In this talk we ask the question how these notions of convergence are related and argue that one characterises them most conveniently using test sequences. We investigate the differences between uniform, point-wise and almost-sure testing, prove Doob-type posterior consistency theorems in various model topologies and consider hypothesis testing problems like Cover's rational mean problem (Cover, 1973). To achieve frequentist posterior consistency, we combine almost-sure tests with a prior condition that generalises Schwartz's KL-condition and is conjectured also to accomodate `tailfree' behaviour like that of Dirichlet posteriors. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Martedi' 17 dicembre 2013 alle ore 16 presso l'aula 1BC50 del Dipartimento di Matematica di Padova il Prof. Fabio Martinelli (Dip. di Matematica, Universita' di Roma Tre) terra' il seguente seminario Title: Time scales separation and dynamical heterogeneities in the East model. Abstract: The East model is a finite linear Markov chain of 0-1 spins, evolving according to a very simple rule: i) with rate 1 and independently for each vertex, a new value 1/0 is proposed with probability 1-q and q respectively; ii) the proposed value is accepted iff the spin immediately to the left is 0. The model and its generalizations play an important role as models of the dynamics of real glasses. The parameter q, which turns out to be the density of the zeros (the facilitating spins) in the stationary measure, is assumed to be very small. In the physical literature this setting corresponds to a low temperature case. We will examine the problem of dynamic heterogeneity, i.e. non-trivial spatio-temporal fluctuations of the local relaxation to equilibrium. A key result will be a very precise computation of the relaxation time of the chain as a function of q and of its length, which uses induction on length scales on one hand and a novel algorithmic lower bound on the other. Our findings reject non rigorous approaches based on numerical simulations. We will conclude with a conjecture due to D. Aldous and P. Diaconis about the scaling limit of the East chain as q-->0.

This phenomenon is not following a random memory-less process and its timing is reflected in hazard rates, with respect to both relapse and mortality, showing multimodal shapes. From a biomedical perspective, such a behavior may be explained by tumor dormancy, i.e. for some patients microscopic tumor foci may remain asymptomatic for a prolonged time interval and, when they escape from dormancy, micrometastatic growth results in a clinical disease appearance. The activation of the growth phase at different metastatic states would explain the occurrence of metastatic recurrences and mortality at different times (multimodal hazard). We place this phenomenon in the framework of survival frailty models. We propose a new statistical approach which models the risk function by considering possible effects of Gamma frailty and compound Poisson fraity in acting on components of the hazard function. Thus, the individual hazard rate is the product of a random frailty variable and the sum of basic hazard rates. The basic hazard rates correspond to micrometastatic developments starting from different initial states. The frailty variable represents the heterogeneity between patients with respect to relapse, which might be related to unknown mechanisms that regulate tumor dormancy. The model is applied to analyze the mortality of patients in a large breast cancer dataset. We show how this framework can appropriately model the tumor dormancy phenomenon and possibly improve the understanding of this biological process.

AVVISO DI SEMINARIO AL GSSI - L'Aquila Giovedi 12 dicembre prossimo alle ore 16 presso il Gran Sasso Science Institute il *Prof. Paolo Dai Prà* terrà un seminario dal titolo: *Strategic interaction in trend-driven dynamics* *Abstract*: We propose a stochastic dynamics in which N agents update their state simultaneously but not independently. At each time step agents aim at maximizing their individual payoff, depending on their action, on the global trend of the system and on a random noise. In the limit of infinitely many agents, a law of large numbers is obtained; the limit dynamics consist in an implicit dynamical system, possibly multiple valued. For a special model, we determine the phase diagram for the long time behavior of these limit dynamics and we show the existence of a phase, where a locally stable fixed point coexists with a locally stable periodic orbit. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

(scusandomi in anticipo per eventuali ripetizioni) ANNUNCIO DI SEMINARIO Il Prof. GEORGE YIN della Wayne State University di Detroit terra' il seguente seminario il lunedi' 9 dicembre alle ore 11.30 nella sala riunioni del VII piano, scala B, del Dipartimento di Matematica, via Trieste 63, Padova: Titolo: SWITCHING DIFFUSION SYSTEMS AND APPLICATIONS ABSTRACT: Numerous problems in control and optimization require the treatment of systems in which continuous dynamics and discrete events coexist. The discrete component is represented by a random jump process with a finite state space, and the continuous component is the solution of a stochastic differential equation. Seemingly similar to diffusions, the processes have a number of salient features distinctly different from diffusion processes. After providing motivational examples arising from wireless communications, identification, finance, singular perturbed Markovian systems, manufacturing, and consensus controls, we present necessary and sufficient conditions for the existence of unique invariant measure, stability, stabilization, and numerical solutions of control and game problems.

Il giorno martedì 3 dicembre alle ore 14.30 presso la aula seminari del Dipartimento di Statistica e Metodi Quantitativi della Università di Milano Bicocca, al IV piano dell'edificio U7, il dott. Giovanni Puccetti della Università di Firenze terrà un seminario su The Rearrangement Algorithm: a new tool for computing bounds on risk measures Abstract: We introduce a numerical algorithm which allows for the computation of sharp upper and lower bounds on the Value-at-Risk or on the Expected Shortfall of high-dimensional risk portfolios having fixed marginal distributions. These bounds can be interpreted as a measure of model uncertainty induced by possible dependence scenarios. We also illustrate several recent applications of the algorithm to quantitative risk management and applied probability. Tutti gli interessati sono invitati a partecipare.

Based on higher order asymptotic theory for likelihood, we propose a directional test whose p-value is computed using one-dimensional integration. For discrete responses this extends the development of Davison et al. (2006), and some of our examples concern testing in contingency tables. For continuous responses the work extends the directional test of Cheah et al. (1994). Examples and simulations illustrate the high accuracy of the method, which we compare with the usual likelihood ratio test and with an adjusted version due to Skovgaard (2001). In high-dimensional settings, such as covariance selection, the approach works essentially perfectly, whereas its competitors can fail catastrophically. Extensions to non-linear exponential families and to general models are also sketched (joint with A.C. Davison, D.A.S. Fraser, N. Reid).

**************************************************************** STATISTICS SEMINARS - COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 29 novembre 2013, alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: François CARON (University of Oxford) A BAYESIAN NONPARAMETRIC MODEL FOR UNDIRECTED AND MULTI-EDGES NETWORKS Abstract: In this talk, I will present ongoing work on a Bayesian nonparametric specification for either undirected or multi-edge directed networks, building on the framework of completely random measures. The formulation allows for an unbounded number of nodes in the network, while encouraging a sparse set of interactions. Importantly, as demonstrated empirically, the model captures salient features of real world networks like power-law degree distributions with possible exponential cut-off in the tails. These properties, in addition to sparsity, are determined by three hyperparameters. I will also discuss an approach for scaling computations to large networks. This is joint work with Emily Fox (University of Washington). Tutti gli interessati sono invitati a partecipare.

Maggiori informazioni sui seminari e mini-corsi presso il DSS sono consultabili a quest'indirizzo: http://goo.gl/Y6OQYm Saluti Pierpaolo Brutti --- Abstract A partire da Ronald Fisher, il concetto di funzione di verosimiglianza ha ricoperto un ruolo fondamentale nell'inferenza statistica. Vi è, però, una varietà di situazioni in cui il calcolo della funzione di verosimiglianza non è agevole oppure non è opportuno. In molti modelli per dati dipendenti la verosimiglianza è onerosa o addirittura impossibile da calcolare a causa delle presenza di matrici di covarianza di grandi dimensioni, di costanti di normalizzazione complesse o di integrali multidimensionali che non possono essere risolti in forma chiusa. Altre difficoltà nell'utilizzo della funzione di verosimiglianza provengono dalla presenza di parametri di disturbo di alta dimensionalità che non permettono una corretta inferenza sui parametri di interesse o dalla disponibilità di un elevato numero di potenziali regressori rispetto al numero di osservazioni. Per risolvere questi e altri problemi, sono state proposte in letteratura diverse estensioni e modifiche del concetto di verosimiglianza. L'obiettivo di questo corso è presentare una rassegna di alcune di queste modifiche, privilegiando le idee e le motivazioni che ne stanno alla base. Programma del corso - Richiami di inferenza di verosimiglianza - Inferenza di verosimiglianza per modelli mal specificati - Sovradispersione e quasi-verosimiglianza - Equazioni di stima generalizzate - Verosimiglianze composite - Verosimiglianze penalizzate per la scelta fra modelli

Thanks to the combination of potentialities from these two scientific areas, the proposed class of models has important advantages with respect to classical techniques used in spatial data analysis. The models are able to efficiently deal with data distributed over irregularly shaped domains, including Riemannian manifold domains, only few methods existing in literature for this type of data structures. Moreover, they can incorporate problem-specific priori information about the spatial structure of the phenomenon under study, with a very flexible modeling of space variation, allowing naturally for anisotropy and non-stationarity. The models have a generalized additive framework with a regularizing term involving a differential quantity of the surface of spatial field to be estimated. The estimators have good inferential properties; moreover, thanks to the use of numerical analysis techniques, they are computationally highly efficient. The method is illustrated in various applied contexts, including data coming from eco-dopplers, three-dimensional angiographies and computational fluid dynamics simulations. The seminar is based on joint work with Laura Azzimonti, Bree Ettinger, Fabio Nobile, Simona Perotto, Jim Ramsay, Piercesare Secchi. This line of research is developed within the FIRB2008 Futuro in Ricerca research project SNAPLE (http://mox.polimi.it/users/sangalli/firbSNAPLE.html ).

*Avviso Seminario* La Dott.ssa Alessandra Bianchi (Università di Padova) terrà un seminario Venerdì 22 Novembre alle ore 11:30 in Aula VII - Dipartimento di Scienze Fisiche, Informatiche e Matematiche - Edificio Matematica - Via Campi 213/B - Modena. Titolo del Seminario: "Random Walk in a one-dimensional Levy random environment" Abstract: In this talk we introduce a model for a one-dimensional Levy-Lorentz gas corresponding to a random walk in random environment on the line. The environment is provided by a renewal point process with inter-distances having a Levy-type distribution, that can be seen as a set of randomly arranged static scatterers. We investigate the quenched behavior of the walk in the case of inter-distances having finite mean but infinite variance and provide asymptotic results about its distribution and moments . In particular we show that, contrary to the annealed case, the quenched behavior of the motion is diffusive. This is a work in progress with G. Cristadoro, M. Lenci and M. Ligabò. L'evento è organizzato nell'ambito del progetto FIRB "Processi stocastici e sistemi di particelle interagenti": http://www.stochastics.unimore.it/firb/

SPEAKER: Francesco Morandin AFFILIATION: Università di Parma TITLE: Anomalous dissipation in a stochastic inviscid shell model of turbulence ABSTRACT: Shell models of turbulence are infinite systems of coupled nonlinear equations with exponentially-growing coefficients. They are thought to be able to capture some of the statistical properties and features of three-dimensional turbulence, while presenting a structure much simpler than Navier-Stokes and Euler equations. We introduce a stochastic version with multiplicative noise of some of these models and prove energy dissipation in spite of its formal conservativity. ------- David Barbato Università di Padova ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

For large n, a typical realization locally behaves like the Galton-Watson tree with Poisson offspring distribution with mean c. We discuss large deviations from this typical behavior, within the framework of the local weak convergence introduced by Benjamini-Schramm and Aldous-Steele. The associated rate function is expressed in terms of an entropy functional on unimodular measures and takes finite values only at measures supported by trees. Along the way, we present a new configuration model which allows one to sample uniform random graphs with a given finite neighborhood distribution, provided the latter is supported by trees. We also present a new class of unimodular random trees, which generalizes the Galton-Watson tree with given degree distribution to the case of neighborhoods of arbitrary finite depth. This is joint work with Charles Bordenave. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A. Moro, 2 00186 Rome - Italy

For the case of two-piece models, Jeffreys priors are shown not to allow for Bayesian inference in the wide and practically relevant class of distributions obtained by skewing scale mixtures of normals. Easily checked conditions under which independence Jeffreys priors can be used for valid inference are derived. In the context of scalar skew-symmetric models, it is shown that the Jeffreys prior of the skewness parameter is symmetric about 0, proper, and with tails O(λ^(−3/2)) under mild regularity conditions. Sufficient conditions for the existence of the posterior distribution induced by the independence Jeffreys prior are investigated for the case when the sampling model belongs to the family of skew-symmetric scale mixtures of normal distributions.

This is complemented by our mentoring program, language courses, soft-skills seminars, travel support for summer schools and conferences, and special funding for students with children. Our seven main research areas are: * Differential geometry, global analysis and mathematical physics * Algebraic and arithmetic geometry, number theory * Probability, statistics and financial mathematics * Discrete mathematics and combinatorial optimization * Geometry, topology and visualization * Numerical mathematics and scientific computing * Applied analysis and differential equations The graduate program starts with three to four semesters of course work (Phase I) leading to a master's degree. This is followed by four to six semesters of thesis research (Phase II) leading to a doctoral degree at one of the three universities. Students who will have completed their bachelor's degree by October 2014 can apply to Phase I; those who will have completed their master's degree by this date can apply to start directly in Phase II. Complete information about applying to the BMS is available online: http://www.math-berlin.de/images/Guidelines2013.pdf Deadline for admission with scholarship: 15 December 2013 Deadline for admission only: 15 May 2014 Website: http://www.math-berlin.de/application Contact: E-Mail: applications(a)math-berlin.de phone: +49 30 314-78651 http://www.math-berlin.de Paolo Dai Pra Via Trieste, 63 35121 Padova Tel. +39 0498271361 Fax +39 0498271428 daipra(a)math.unipd.it

Seminario di Probabilità - Università di Padova

16 Oct '13

Ho il piacere di invitarvi al seguente seminario, che si terrà lunedì 21 ottobre, alle ore 15:00, nell'aula 2BC30 della Torre Archimede presso il Dipartimento di Matematica dell'Universita` degli Studi di Padova. SPEAKER: Dott.ssa Alessandra Cipriani AFFILIATION: Institute of Mathematics, University of Zurich TITLE: Thick points for a Gaussian Free Field in 4 dimensions ABSTRACT: This joint work with Rajat Subhra Hazra is concerned with the study of the fractal dimension of thick points for a 4-dimensional Gaussian Free Field. We adopt the deﬁnition of Gaussian Free Field on R^4 introduced by Chen and Jakobson (2012) viewed as an abstract Wiener space with underlying Hilbert space H^2(R^4). We can prove that for 0 ≤ a ≤ 4 the Hausdorﬀ dimension of the set of a-high points is 4 − a, and we show that this set is the support of the 4-dimensional Liouville quantum gravity measure. -- Alessandra Bianchi Dip. di Matematica Pura e Applicata Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

seminario Elena di Bernardino in Bicocca
by Fabio Bellini 16 Oct '13

16 Oct '13

Il giorno martedì 22 ottobre alle ore 14.30 presso la aula seminari del Dipartimento di Statistica e Metodi Quantitativi dell' Università di Milano-Bicocca, al IV piano dell' edificio U7, la dott.ssa Elena di Bernardino del CNAM di Parigi terrà un seminario dal titolo On Multivariate Extensions of Value-at-Risk Abstract: In this paper, we introduce two alternative extensions of the classical univariate Value-at-Risk (VaR) in a multivariate setting. The proposed multivariate VaR are real-valued risk measures constructed from the level sets of multivariate distribution and multivariate survival functions. Several properties have been derived. In particular, we show that these risk measures satisfy the positive homogeneity and the translation invariance property. Comparisons between univariate risk measures and components of multivariate VaR are provided. We also analyze how these measures are impacted by a change in marginal distributions, by a change in the dependence structure and by a change in the risk level. Illustrations are given in the class of Archimedean copulas. (joint work with A. Cousin) Tutti gli interessati sono invitati a partecipare.

Scusandomi per eventuali ripetizioni, segnalo questa utile iniziativa dell'UMI, che sta avendo diffusione attraverso vari altri canali matematici. Io mi sono appena registrato.

L'iniziativa ha molteplici finalita. Per prima cosa essa vuole costituire un segnale di attenzione dell'UMI verso i tanti matematici italiani che, per un motivo o per un altro, svolgono la loro attivita all'estero. L'UMI vuole cosi mostrare che la lontananza geografica non necessariamente deve intaccare il legame scientifico, culturale ed anche affettivo (in senso lato) che lega i nostri colleghi italiani all'estero alla nostra comunita. In secondo luogo, la mappa puo essere utile anche agli stessi matematici italiani residenti all'estero, in quanto puo aiutare a metterli in contatto tra loro dal punto di vista scientifico e non solo. Infine, e per quanto riguarda l'UMI, non ultimo, vi e l'obiettivo di riuscire ad avere in modo realistico e visibile, un quadro del fenomeno, purtroppo sempre piu significativo, della cosiddetta "fuga dei cervelli". Questo quadro potra avere un valore non solo statistico, ma politico, per aiutarci a mostrare a chi dirige le sorti della ricerca in Italia, la vastita e la gravita del fenomeno, cui si dovrebbe porre rapido rimedio offrendo, soprattutto ai giovani, pronte e competitive opportunita di ingresso nel mondo del lavoro intellettuale. L'inserimento nella mappa avviene su base volontaria e al momento gia piu di 200 persone si sono iscritte. Confido che ciascuno di voi voglia appoggiare questa iniziativa dando ad essa la massima pubblicita ed invitando colleghi italiani all'estero ad iscriversi alla mappa. Per concludere, colgo l'occasione per ringraziare i colleghi dianzi citati nonche Marcello Villani che ha creato il sito e la segreteria di Bologna per aver collaborato, con la consueta solerzia, a rendere l'iniziativa possibile. Ogni ulteriore suggerimento sara benvenuto.

11 Oct '13

NUOVO SERVER PER LA LISTA RANDOM, OVVERO QUALCOSA DEVE CAMBIARE PERCHÉ TUTTO RESTI COME PRIMA Cari iscritti Benvenuti nella lista Random, nella sua rinnovata veste. Ringraziamo Gustavo Posta e Marco Isopi per averci concesso l'onore, più che l'onere, di ospitare la lista storica che ormai da anni è il riferimento della probabilità in Italia. Intendiamo mantenere tutte le caratteristiche che Gustavo e Marco avevano dato alla lista, prima tra tutte la facoltà di ogni iscritto di inviare liberamente i propri messaggi. L'unica accortezza è che da oggi l'indirizzo a cui spedire i propri messaggi è random(a)mail.dm.unipi.it La nuova versione della lista è ospitata sui server del dipartimento di matematica dell'università di Pisa, che ringraziamo per la gentile ospitalità. Gli iscritti alla vecchia lista Random sono automaticamente iscritti alla nuova. Presto trasferiremo anche gli archivi della vecchia lista. Chiunque voglia de-iscriversi oppure modificare le proprie opzioni di sottoscrizione può visitare la pagina http://mail.dm.unipi.it/listinfo/Random Cogliamo infine l'occasione per ringraziare Gustavo e Marco per il loro egregio lavoro. Speriamo di poter continuare a garantire un valido servizio alla comunità come i nostri predecessori. Per questo, consigli e suggerimenti sono graditi e ben accetti. Francesco Caravenna e Marco Romito
