seminario Emilio Porcu a Roma Tor Vergata
by Anna Vidotto 30 Oct '19

30 Oct '19

Dear all, I would like to announce the following talk that will be held on Thursday *November* *7th* 2019, at *5 PM*, in *Aula D’Antoni* of the Department of Mathematics, University of Rome Tor Vergata. *Speaker:* Emilio Porcu (Trinity College Dublin) *Title:* Modeling Temporally Evolving and Spatially Globally Dependent Data *Abstract:* The last decades have seen an unprecedented increase in the availability of data sets that are inherently global and temporally evolving, from remotely sensed networks to climate model ensembles. This paper provides an overview of statistical modeling techniques for space–time processes, where space is the sphere representing our planet. In particular, we make a distinction between (a) second order‐based approaches and (b) practical approaches to modeling temporally evolving global processes. The former approaches are based on the specification of a class of space–time covariance functions, with space being the two‐dimensional sphere. The latter are based on explicit description of the dynamics of the space–time process, that is, by specifying its evolution as a function of its past history with added spatially dependent noise. We focus primarily on approach (a), for which the literature has been sparse. We provide new models of space–time covariance functions for random fields defined on spheres cross time. Practical approaches (b) are also discussed, with special emphasis on models built directly on the sphere, without projecting spherical coordinates onto the plane. We present a case study focused on the analysis of air pollution from the 2015 wildfires in Equatorial Asia, an event that was classified as the year's worst environmental disaster. The paper finishes with a list of the main theoretical and applied research problems in the area, where we expect the statistical community to engage over the next decade.

Depending on the schedule, some posters will be selected for longer contributed presentations throughout the week. If you are applying for a travel grant, then you are required to submit your poster abstract by Friday, November 15, 2019. *Summary:* This workshop continues discussions and explorations started in January 2016 and January 2018 at the first and second editions of the workshop. A revolution in statistics and machine learning (ML) is underway. Modern algorithms can now learn high level abstractions via hierarchical models, leading to break-through accuracy in benchmarks for computer vision, language, etc. Underlying these advances is a strong and deep connection to various aspects of applied mathematics and statistical physics. For example, proper choice of statistical force allows to screen interaction and learn graphical models governing multi-dimensional distributions efficiently, gauge transformations from physics guide incorporation of symmetries in the neural network design, dynamical system interpretation helps to understand and improve performance of most efficient deep learning schemes, etc. This workshop seeks perspectives on leveraging the deep connection between ML and physics, but now with the goal to better understand and model physical systems, static and dynamic. We invite experts both in machine learning techniques as well as domain science applications. In this third edition of PIML we will focus on applications of interest to our LANL and DOE sponsors, specifically on improving scale-reduced, large eddy modeling and simulations of turbulence that arise in various mechanical-engineering, aerospace and climate applications; building reduced models for infrastructures (energy systems, cyber-physical systems, etc.); guiding development of inverse/design approaches in quantum physics, e.g. related to tensor networks; designing new computational paradigms (such as related to quantum and neuromorphic computing). The workshop discussions are aimed towards approaches and methods for physical modeling applications where a big-data, black-box approach to ML is only a starting point. We seek participants who may suggest innovative approaches that extend application agnostic ML techniques by incorporating complex constraints imposed by physical principles (e.g. conservation laws, causality, symmetries, entropy principles and related). The workshop format assumes 7 talks a day, late afternoon discussions and poster session. We encourage application of young researchers for fellowships (see website for details). We plan for active participation of LANL researchers and program managers across directorates and divisions interested in the physics informed learning. This emerging area of research has many aspects of computational co-design, and draws on LANL's strengths in statistical physics, modern applied mathematics, theoretical and applied computer science, infrastructure modeling and simulations, fluids and materials modeling, and high performance computing. Looking forward, we view physics informed learning as a viable path for LANL and DOE toward truly predictive multi-scale modeling, optimization, inference and leading for plethora of relevant applications in sciences and engineering. *Organizing Committee:* Michael Chertkov (University of Arizona) Andrey Lokhov (Los Alamos National Laboratory) Arvind Mohan (Los Alamos National Laboratory) [image: bed3f21384084acb905f2c173a3fa658.jpg]

seminario Claudio Macci a Pisa
by Dario Trevisan 28 Oct '19

28 Oct '19

Dear all, this is to announce the following research talk by Claudio Macci, to be held in Pisa. PLACE: Sala Seminari, Dipartimento di Matematica, Università di Pisa (first floor). DATE & TIME: Wednesday, Nov 6, 2019, 3 PM SPEAKER: Claudio Macci (Università Roma Tor Vergata) TITLE: Multivariate fractional (possibly compound) Poisson processes ABSTRACT: we present multivariate space-time fractional Poisson processes by considering common random time-changes of a finite-dimensional vector of independent classical (nonfractional) Poisson processes. In some cases we also consider compound processes. We obtain some equations in terms of some suitable fractional derivatives and fractional difference operators, which provides the extension of known equations for the univariate processes. In particular we show that, for each fixed $t\geq 0$, the conditional joint distribution of the components given their sum is multinomial, as happens for the nonfractional Poisson processes. Thus we consider a suitable multivariate "alternative" fractional Poisson process, and we study its asymptotic behavior for large times (large and moderate deviations). The results appear in two papers with Luisa Beghin.

Seminario a Padova: Alekos Cecchin

Seminario di Analisi e Probabilità all'Università di Padova Martedì 29 ottobre 2019 alle ore 14:30 in aula seminario 430 del Dipartimento di Matematica (via Trieste, 63, 35121 Padova) Alekos Cecchin (Université de Nice Sophia-Antipolis, France) terrà un seminario dal titolo "Selection by vanishing common noise for potential finite state mean field games" Abstract: By adding a suitable Wright-Fisher common noise in the dynamics of the law, uniqueness is restored for finite state mean field games, for any shape of the costs. We then focus on a class of mean field games in which the costs admit a potential in the simplex of probability measures. Firstly, by modifying the cost in the mean field game, we show that the unique solution of the randomized mean field game is equal to the unique minimizer of a suitable stochastic control problem stated in the simplex, called potential randomized game. Thus we study the limit as the intensity of the common noise vanishes. On the one hand, the optimal trajectories converge to the mean field game solutions which are minimizers of the corresponding potential game (not randomized), that is a deterministic optimal control problem in the simplex. On the other hand, the classical solution to the second order master equation converges to the gradient of the value function of the related potential game; we select a particular weak solution, in the sense of distributions, of the master equation, which can be written as multidimensional system of hyperbolic PDEs stated in the simplex. Lastly, we establish uniqueness of such solution in a suitable class. Joint work with Francois Delarue. Tutti gli interessati sono invitati a partecipare.

Seminario di probabilita' di Daniel Valesin (Groningen) a Roma Tre
by Alexandre Stauffer 24 Oct '19

SEMINARIO Probabilita' Daniel Valesin (University of Groningen) Titolo: On the threshold of spread-out contact process percolation Lunedi' 04 Novembre 2019 ORE 16:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We study the stationary distribution of the (spread-out) d-dimensional contact process from the point of view of site percolation. In this process, vertices of ^d can be healthy (state 0) or infected (state 1). With rate one infected individuals recover, and with rate lambda they transmit the infection to some other vertex chosen uniformly within a ball of radius R. The classical phase transition result for this process states that there is a critical value lambda_c(R) such that the process has a non-trivial stationary distribution if and only if lambda > lambda_c(R). In configurations sampled from this stationary distribution, we study nearest-neighbor site percolation of the set of infected sites; the associated percolation threshold is denoted lambda_p(R). We prove that lambda_p(R) converges to 1/(1-p_c) as R tends to infinity, where p_c is the threshold for Bernoulli site percolation on ^d. As a consequence, we prove that lambda_p(R) > lambda_c(R) for large enough R, answering an open question of [Liggett, Steif, AIHP, 2006] in the spread-out case. Joint work with Bala'zs Ra'th.

Mini corso di A. Stauffer a Roma Tre: Multi-scale analysis of reaction-diffusion particle systems
by Pietro Caputo 22 Oct '19

22 Oct '19

Speaker: Alexandre Stauffer (Roma Tre) Title: Multi-scale analysis of reaction-diffusion particle systems 6 Lectures: Monday, 25 November at 16:30 Tuesday, 26 November at 14:30 Monday, 2 December at 16:30 Tuesday, 3 December at 14:30 Monday, 9 December at 16:30 Tuesday, 10 December at 14:30 All lectures will be in Room 211 (2nd floor) at Department of Mathematics and Physics of Roma Tre Largo San Murialdo 1, Palazzina C For PhD students that want to take the course as part of their PhD coursework, the course will be completed by a reading part (to be discussed with the lecturer). Abstract: This course focus on the (microscopic) analysis of stochastic processes on particle systems. A few examples include spread of infection among moving particles, the frog model or stochastic combustion model, activated random walks, growth processes with competition, and branching random walk with interactions. A common feature of such models is that correlations do not decay exponentially fast, which brings serious challenges to the application of standard techniques of analysis, such as renormalization techniques and comparison with independent percolation. Recently, there has been very important progress in this field, with most new results employing a so-called multi-scale analysis to control the dependences in the model. Multi-scale analysis proved to be an extremely powerful technique; it has been employed in areas beyond particle system, one notable example being the study of random interlacements, where it has been playing a fundamental role. Despite its power, a multi-scale analysis can be quite involved to implement and can become very technical. In particular, it usually needs to be developed from scratch for each application as it needs to be tailored to each specific question being analyzed. The goal of this course is to explain the multi-scale analysis in a didactic and comprehensible way, demystifying this technique, and explaining its main aspects (the ones that are common to most applications) and the most common variations. In order to do this we will concentrate on one problem: the analysis of the spread of an infection among particles that move as independent simple random walks.

Seminar Cadonna @Bocconi
by Giacomo Zanella 18 Oct '19

18 Oct '19

We announce the following DEC Statistics seminar: Thursday, October 24 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Annalisa Cadonna (Wirtschaftsuniversität Wien) Title: Hierarchical shrinkage in time-varying parameter models through the Triple Gamma prior Abstract: Time varying parameter (TVP) models are widely used in time series analysis, because of their flexibility and ability to capture gradual changes in the evolution dynamics of the model variables. The popularity of TVP state-space models in macroeconomics and finance is based on the evidence that, in most applications, the influence of certain predictors on the outcome variables varies over time. The risk of overfitting in TVP models is a well know issue, which increases with the dimension of the problem at hand, as only a small subset of the predictors might actually have a dynamic influence on the output variables. Hence, in the last decade, there has been a growing need for models and methods able to discriminate between time varying and static parameters in TVP models or, in other words, perform variance selection. We propose a new global local shrinkage prior for shrinkage of variances in TVP models, referred to as the Triple Gamma prior. The Triple Gamma prior extends to variance selection the Normal-Gamma-Gamma prior introduced in Griffin and Brown (2017) in the context of highly structured regression models. The Triple Gamma prior accommodates, as special or limit cases, the Bayesian Lasso, the Double Gamma prior, and the popular Horseshoe prior. Interesting properties of the triple gamma prior are outlined and an efficient Markov Chain Monte Carlo algorithm is developed. An extended simulation study is conducted and the proposed modeling approach is applied to real data, both in a univariate and a multivariate framework. The predictive performance of different shrinkage priors is compared in terms of log predictive density scores. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

Spring School COMPLEX NETWORKS: THEORY, METHODS, AND APPLICATIONS (6th edition)
by Irene Crimaldi 16 Oct '19

16 Oct '19

Spring School COMPLEX NETWORKS: THEORY, METHODS, AND APPLICATIONS (6th edition) Lake Como School of Advanced Studies Villa del Grumello, Como, Italy, 18-21 May 2020 https://ntmf.lakecomoschool.org/ *** DEADLINE FOR APPLICATION: February 23, 2020 *** Many real systems can be modeled as networks, where the elements of the system are nodes and interactions between elements are edges. An even larger set of systems can be modeled using dynamical processes on networks, which are in turn affected by the dynamics. Networks thus represent the backbone of many complex systems, and their theoretical and computational analysis makes it possible to gain insights into numerous applications. Networks permeate almost every conceivable discipline---including sociology, transportation, economics and finance, biology, and myriad others---and the study of "network science" has thus become a crucial component of modern scientific education. The school "Complex Networks: Theory, Methods, and Applications" offers a succinct education in network science. It is open to all aspiring scholars in any area of science or engineering who wish to study networks of any kind (whether theoretical or applied), and it is especially addressed to doctoral students and young postdoctoral scholars. The aim of the school is to deepen into both theoretical developments and applications in targeted fields.

Colloquium di Lorenzo Zambotti a Milano-Bicocca (lunedì 28 ottobre)
by Francesco Caravenna 15 Oct '19

15 Oct '19

Ho il piacere di annunciare il seguente Colloquium del Dipartimento di Matematica e Applicazioni, Università di Milano-Bicocca, congiuntamente con il Seminario Matematico e Fisico di Milano. Il giorno lunedì 28 ottobre 2019, alle ore 16:00, Lorenzo Zambotti (Sorbonne Université, Paris) terrà un colloquium dal titolo "Regularity structures: from physics to probability, from analysis to algebra, from combinatorics to geometry" Il seminario si terrà nell'aula 3014 (edificio U5, terzo piano, via Cozzi 55, Milano) e sarà seguito da un rinfresco. Segue l'abstract. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% Abstract: In this talk I wish to present some of the ideas at the heart of the theory of regularity structures (RS), introduced by Martin Hairer in 2014. RS are perhaps best described as a theory of Taylor expansions in a fractal (random) setting. I plan to show how this theory is based on a fascinating interplay between several different disciplines, as announced by my title. %%%%%%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Looking forward to your participation, Fabio Ancona, Paolo Dai Pra, Franco Rampazzo ---------------------------------------------------------------- *** Half day in Stochastic Analysis and applications *** Wed. 30 Oct. 2019, Aula 1C150 Maths Department, Padova ---------------- *** Special Guest: THERRY LYONS (Oxford) *** *** Opening the workshop at 10:30*** ---------------- *** Speaker: FRANCO FLANDOLI (SNS Pisa)*** *** Seminar at 11:05*** *** Title: Effect of transport noise on PDEs *** *** Abstract *** Linear PDEs of transport type are regularized by the addition of an extra transport term of stochastic type; this is a phenomenon discovered around 2010 and consolidated by different techniques and on different examples. However, the effect on nonlinear PDEs is much less clear. Two results for point vortex solutions and point charge solutions of 2D Euler equations and 1D Vlasov-Poisson equations respectively, indicate that a rich noise has to be considered, opposite to the linear case where a simple space-independent noise suffices to regularize. Some confirmations that such rich noise may have regularizing properties on nonlinear models came for Leray alpha model and dyadic models of turbulence. We now have new insight in the case of 2D Euler equations and 3D Navier-Stokes equations, that will be explained in the talk. The results mentioned above, the classical and the new ones, have been obtained by several authors including Gubinelli, Priola, Barbato, Galeati, Luo and myself. ---------------- *** Speaker: FRANCESCO CARAVENNA (Milano Bicocca) *** *** Seminar at 11:40 *** *** Title: On the two-dimensional KPZ equation *** *** Abstract: *** We consider the Kardar-Parisi-Zhang (KPZ) equation in two space dimensions, driven by space-time white noise. This is a singular PDE which lacks a solution theory, so it is standard to consider a regularized version of the equation and then to investigate the behavior of the solution when the regularization is removed. We first show that the regularized solution undergoes a phase transition, as the noise strength is varied on a logarithmic scale. Then, in the sub-critical regime, we prove convergence (after centering and rescaling) to an explicit well-posed random PDE, the additive Stochastic Heat Equation, with a non-trivial constant on the noise. Based on joint works with Rongfeng Sun and Nikos Zygouras. ---------------- *** Speaker: FRANCO RAMPAZZO (Padova) *** *** Seminar at 12:15 *** *** Title: Limit solutions for control-affine nonlinear systems of ode's *** *** Abstract: *** The aim of this talk, which is fully devoted to deterministic input-output systems, is to present the extremely weak notion of 'limit solution', that might be (or might be not) of interest also for whom is more interested in Stochastic Analysis. For a nonlinear (deterministic) control system with a given initial condition and with a dynamics which is affine in the control variable, a 'limit solution' verifies the following properties: i) it is pointwise defined for an input which is (formally) the derivative of a Lebesgue integrable function; ii) in the commutative case (i.e. when all Lie brackets of the involved vector field vanish identically) the limit solution coincides with the solution one can obtain via a (existing) change of coordinates which makes all vector fields constant; iii) the notion of limit solution subsumes former concepts of solution valid for the generic, non-commutative case. In particular, when the control is the derivative of a bounded variation path, a quite clear relation is established between limit solutions and so-called 'graph completion' solutions.

Seminario di Antonio Blanca a Roma Tre il 24-10-2019

Speaker: Antonio Blanca (Penn State University) Titolo: Lower bounds for testing spin systems Giovedi' 24 Ottobre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We study the identity testing problem in the context of spin systems where it takes the following form: given the parameter specification of the model M and a sampling oracle for the distribution μ of an unknown model M*, can we efficiently determine if the two models M and M* are the same? We establish hardness results for this problem for two prototypical spin systems: the Ising model and proper colorings. For the ferromagnetic (attractive) Ising model, Daskalakis et al. (2018) presented a polynomial-time algorithm for identity testing. I will present a hardness result for the antiferromagnetic (repulsive) setting. In our proofs, we use random graphs as gadgets; this is inspired by similar constructions in seminal works on the hardness of approximate counting. The results for proper colorings are based on the presumed hardness of #BIS, the problem of (approximately) counting independent sets in bipartite graphs. Based on joint work with Ivona Bezakova, Zongchen Chen, Daniel Stefankovic and Eric Vigoda

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 18 Ottobre 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Mark PODOLSKIJ (Aarhus University) OPTIMAL ESTIMATION OF CERTAIN RANDOM QUANTITIES ASSOCIATED WITH LEVY PROCESSES In this talk we present new ideas on optimality of statistical estimates of certain random quantities of stochastic processes, such as supremum or local times. Despite the existing results on estimation of such objects through high frequency observations, the question of optimality is rarely discussed. We will demonstrate some optimal estimation methods for the supremum and local times of the Brownian motion in the L2 and L1 sense.

******************************************************************** SEMINARI DI PROBABILITÀ E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITÀ DEGLI STUDI DI TORINO ********************************************************************* Martedì 15 Ottobre 2019 alle ore 16:30 in Sala S presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. *Enrico Scalas* (Department of Mathematics – University of Sussex, UK) terrà un seminario dal titolo *Functional and Thermodynamic Limits of a Simple Coagulation-Fragmentation Markov Chain* Abstract: We discuss a simple random exchange model for the distribution of wealth. There are N agents, each one endowed with a fraction of the total wealth; indebtedness is not possible, so wealth fractions are positive random variables. At each step, two agent are randomly selected, their wealths are first merged (coagulation) and then randomly split into two parts (fragmentation) conserving the total wealth. We start from a discrete state space - discrete time version of this model and, under suitable scaling, we present its functional convergence to a continuous space - discrete time model. Then, we discuss how a continuous-time version of the one-point marginal Markov chain functionally converges to a kinetic equation of Boltzmann type. Solutions to this equation are presented and they coincide with the appropriate limits of the invariant measure for the marginal Markov chain. In this way, in this simple case, we complete Boltzmann’s program of deriving kinetic equations from random dynamics.

Seminario Jonathan Hermon a Roma Tre il 15-10-2019

Martedi' 15 Ottobre 2019 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Speaker: Jonathan Hermon Titolo: Anchored expansion in supercritical percolation on nonamenable graphs. Abstract: Let G be a transitive nonamenable graph, and consider supercritical Bernoulli bond percolation on G. We prove that the probability that the origin lies in a finite cluster of size n decays exponentially in n. We deduce that: 1. Every infinite cluster has anchored expansion (a relaxation of having positive Cheeger constant), and so is nonamenable in some weak sense. This answers positively a question of Benjamini, Lyons, and Schramm (1997). 2. Various observables, including the percolation probability and the truncated susceptibility (which was not even known to be finite!) are analytic functions of p throughout the entire supercritical phase. 3. A RW on an infinite cluster returns to the origin at time 2n with probability exp(-Theta(n^{1/3})). Joint work with Tom Hutchcroft.

Seminar Mealli @Bocconi
by Giacomo Zanella 08 Oct '19

08 Oct '19

We announce the following DEC Statistics seminar: Thursday, October 10 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Fabrizia Mealli (University of Florence) Title: Assessing causal effects in the presence of treatment switching through principal stratification Abstract: consider clinical trials focusing on survival outcomes for patients suffering from Acquired Immune Deficiency Syndrome (AIDS)-related illnesses or particularly painful cancers in advanced stages. These trials often allow patients in the control arm to switch to the treatment arm if their physical conditions are worse than certain tolerance levels. The Intention-To-Treat analysis compares groups formed by randomization regardless of the treatment actually received. Although it provides valid causal estimates of the effect of assignment, it does not measure the effect of the actual receipt of the treatment and ignores the information of treatment switching in the control group. Other existing methods propose to reconstruct the outcome a unit would have had if s/he had not switched. But these methods usually rely on strong assumptions, for example, there exists no relation between patient's prognosis and switching behavior, or the treatment effect is constant. Clearly, the switching status of the units in the control group contains important post-treatment information, which is useful to characterize the treatment effect heterogeneity. We propose to re-define the problem of treatment switching using principal stratification and introduce new causal estimands, principal causal effects for patients belonging to subpopulations defined by the switching behavior under control. For statistical inference, we use a Bayesian approach to take into account that (i) switching happens in continuous time generating infinitely many principal strata; (ii) switching time is not defined for units who never switch in a particular experiment; and (iii) survival time and switching time are subject to censoring. We illustrate our framework using a synthetic dataset based on the Concorde study, a randomized controlled trial aimed to assess causal effects on time to-disease progression or death of immediate versus deferred treatment with zidovudine among patients with asymptomatic HIV infection. Joint work with Alessandra Mattei and Peng Ding Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

Seminar announcement
by Marco Scarsini 01 Oct '19

01 Oct '19

Thursday, 3 October, 12:00 Luiss | Viale Romania, 32 | Room 207 Yosi Rinott, Hebrew University of Jerusalem Title Priors and Posteriors of Asset Values, Domination, Optimism, and Monotonicity Abstract Suppose there is a set of states that are relevant to the value of an asset, and the market has a prior distribution on the state space. Consider signals having distribution depending on the true state. The price of an asset depends on the market’s posterior probability that the asset is in a good state, given a signal. Before the signal is given, the market considers the expectation of this (random) posterior probability, and more generally, its distribution. It is well known that the expected posterior equals the prior, but the actual posterior probability may be higher or lower than the prior depending on the signal. Suppose an insider has a different prior than the market. We study the question of what kind of priors will make the insider expect that the asset value following the signal will be higher than the market’s value (suggesting to buy, or to be optimistic). Since the posterior is a random variable, this leads to stochastic ordering, and in fact, we obtain a very strong ordering, namely likelihood ratio order. Given such a setup, if signals are generated independently according to a given state, then Doob’s Bayesian Consistency Theorem says that the posterior probability of this state converges to one. We study some monotonicity properties of this convergence, and some (perhaps) surprising lack of monotonicity. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza Luiss Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Seminario di Claudio Macci presso l’Università di Salerno
by Barbara Martinucci 01 Oct '19

01 Oct '19

Il Prof. Claudio Macci (Università di Roma Tor Vergata) terrà il seguente seminario mercoledì 9 ottobre alle ore 16.00 presso la sala riunioni del Dipartimento di Matematica dell’Università di Salerno: *Titolo*: "Multivariate fractional (possibly compound) Poisson processes " *Abstract:* We present multivariate space-time fractional Poisson processes by considering common random time-changes of a finite-dimensional vector of independent classical (non fractional) Poisson processes. In some cases we also consider compound processes. We obtain some equations in terms of some suitable fractional derivatives and fractional difference operators, which provides the extension of known equations for the univariate processes. In particular we show that, for each fixed t≥0, the conditional joint distribution of the components given their sum is multinomial, as happens for the non fractional Poisson processes. Thus we consider a suitable multivariate "alternative" fractional Poisson process, and we study its asymptotic behavior for large times (large and moderate deviations). The results appear in two papers with Luisa Beghin Cordiali saluti, Barbara Martinucci
