**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 4 Luglio 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Michael J. DANIELS (University of Texas at Austin) A FLEXIBLE BAYESIAN APPROACH TO MONOTONE MISSING DATA IN LONGITUDINAL STUDIES WITH INFORMATIVE MISSINGNESS WITH APPLICATION TO AN ACUTE SCHIZOPHRENIA CLINICAL TRIAL Abstract: We develop a Bayesian nonparametric model for a longitudinal response in the presence of nonignorable missing data. Our general approach is to first specify a {\em working model} that flexibly models the missingness and full outcome processes jointly. We specify a Dirichlet process mixture of missing at random (MAR) models as a prior on the joint distribution of the working model. This aspect of the model governs the fit of the observed data by modeling the observed data distribution as the marginalization over the missing data in the working model. We then separately specify the conditional distribution of the missing data given the observed data and dropout. This approach allows us to identify the distribution of the missing data using identifying restrictions as a starting point. We propose a framework for introducing sensitivity parameters, allowing us to vary the untestable assumptions about the missing data mechanism smoothly. Informative priors on the space of missing data assumptions can be specified to combine inferences under many different assumptions into a final inference and accurately characterize uncertainty. These methods are motivated by, and applied to, data from a clinical trial assessing the efficacy of a new treatment for acute Schizophrenia. Joint work with Antonio Linero at the University of Florida 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: Luciano Campi - presso Dipartimento di Informatica, Università di Verona

Annuncio di Seminario Luciano Campi, London School of Economics, London Giovedi' 3 Luglio, presso il Dipartimento di Informatica, Università di Verona Strada le Grazie, 15 - Sala Verde ore 15:00 (14:45 rinfresco, 15:00 inizio seminario) Title: Utility indifference valuation for non-smooth payoffs with an application to power derivatives Abstract: We consider the problem of exponential utility indifference valuation under the simplified framework where traded and nontraded assets are uncorrelated but where the claim to be priced possibly depends on both. Traded asset prices follow a multivariate Black and Scholes model, while nontraded asset prices evolve as generalized Ornstein-Uhlenbeck processes. We provide a BSDE characterization of the utility indifference price (UIP) for a large class of non-smooth, possibly unbounded, payoffs depending simultaneously on both classes of assets. Focusing then on European claims and using the Gaussian structure of the model allows us to employ some BSDE techniques (in particular, a Malliavin-type representation theorem due to Ma (2002)) to prove the regularity of Z and to characterize the UIP for possibly discontinuous European payoffs as a viscosity solution of a suitable PDE with continuous space derivatives. The optimal hedging strategy is also identified essentially as the delta hedging strategy corresponding to the UIP. Since there are no closed-form formulas in general, we also obtain asymptotic expansions for prices and hedging strategies when the risk aversion parameter is small. Finally, our results are applied to pricing and hedging power derivatives in various structural models for energy markets.

Seminario N. Leonenko a Padova- Mercoledì 2 luglio
by Marco Ferrante 21 Jun '14

21 Jun '14

Annuncio di seminario: Mercoledì 2 Luglio alle ore 12.00 in Aula 2BC30 del Dipartimento di Matematica dell'Università di Padova il Prof. Nikolai Leonenko dell'Università di Cardiff terrà il seminario Titolo: Fractional Pearson diffusions. Abstract: Pearson diffusions have stationary distributions of Pearson type. They includes Ornstein-Uhlenbeck, Cox-Ingersoll-Ross, and several others wellkown processes. Their stationary distributions solve the Pearson equation, developed by Pearson in 1914 to unify some important classes of distributions (e.g., normal, gamma, beta). Their eigenfunction expansions involve the traditional classes of orthogonal polynomials (e.g., Hermite, Laguerre, Jacobi). We develop fractional Pearson di¢ sions ([1],[2]), constructing by a non-Markovian inverse stable time change. Their transition densities are shown to solve a time-fractional analogue to the diffusion equation with polynomial coefficients. Because this process is not Markovian, the stochastic solution provides additional information about the movement of particles that di§use under this model. This is joint work with M.M. Meerschaert and A. Sikorskii (Michigan State Univeraity, USA). Anomalous diffusions have proven useful in applications to physics, geophysics, chemistry, and finance.

Seminario a Padova - Giovedì 26 giugno ore 16
by Marco Ferrante 18 Jun '14

18 Jun '14

Annuncio di seminario: Giovedì 26 giugno alle ore 16.00 in Aula 2AB40 del Dipartimento di Matematica dell'Università di Padova il Prof. Carles Rovira dell'Universitat de Barcelona terrà il seminario Titolo: Stochastic differential equations with non-negativity constraints driven by fractional Brownian Abstract: In this talk, we deal with existence and uniqueness result of solution for stochastic differential driven by a fractional Brownian motion with Hurst parameter $H$ and with reflection. The cases $H >\frac12$ and $H \in (\frac13,\frac12)$ must be considered separately. When $H>\1/2$, we first study an ordinary integral equation where the integral is defined in the Young sense and then we apply this result pathwise to solve the stochastic problem. On the other hand, when H $\in (\frac13,\frac12)$, we consider an existence and uniqueness result of solution for multidimensional delay differential equations with normal reflection and driven by a H\"older continuous function of order $\beta \in (\frac13,\frac12)$.

SINGULAR STOCHASTIC PDEs September 22-24, 2014 Centro di Ricerca Matematica Ennio De Giorgi, Pisa, Italy http://www.crm.sns.it/event/333/ The purpose of the School is to introduce and discuss recent development in the analysis of singular stochastic PDEs arising in Physics, such as the Kardar-Parisi-Zhang equation. In this class of problems the irregularity introduced by the driving noise does not allow to use classical methods from the theory of partial differential equations. The school is aimed at student and young researchers in the field of stochastic PDEs, as well as scholars coming from the fields of the theory of PDE and theoretical physics. The school consists in a series of lectures by Massimiliano Gubinelli, additional invited lectures by Harald Oberhauser, Hendrik Weber, Lorenzo Zambotti and short presentations by participants. REGISTRATION: http://www.crm.sns.it/event/333/registration.html In a few cases funding for local expenses for young participants might be available, but funds are limited.

Il giorno Giovedi 19 Giugno 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Fabio BELLINI (Università di Milano-Bicocca) terra un seminario dal titolo "Risk management with expectiles" Abstract We discuss the main properties of the expectiles, a one parameter family of coherent risk measures introduced in the statistical literature by Newey and Powell (1987). Expectiles are the only coherent risk measures that are also elicitable, in the sense that they can be equivalently defined as the minimizers of an expected loss; this property provides a natural methodology to perform a consistent backtesting. In this talk we explore the potential applicability of expectiles in a capital regulation framework, as an alternative to VaR and CVaR.

Seminar and mini-course by Luca Capriotti, June 19 - 20, SNS Pisa
by Giacomo Bormetti 13 Jun '14

13 Jun '14

Luca Capriotti (EMEA head of Quantitative Strategies Global Credit Products, Credit Suisse) will give a seminar at the Scuola Normale Superiore, Pisa on Thursday 19 June 2014, 13:00 Aula Bianchi. The title and abstract are Ulisse Dini, Adjoint Algorithmic Differentiation and the Efficient Risk Management of Credit Portfolios Adjoint Algorithmic Differentiation (AAD) is one of the principal innovations in risk management of the recent times. In this talk I will show how AAD can be used to risk manage in real time credit products, both exotic and vanilla, whether valued with Monte Carlo or with semi-analytical methods. I will show how by combining adjoint ideas with the implicit function (Dini's) theorem one can avoid repeating multiple times the calibration of the hazard rate curves which, especially for flow products, often represent the bottle neck in the computation of spread and interest rate risk. This typically results in orders of magnitudes savings in computation time with respect to standard methods. The adjoint of the calibration step can be naturally combined with the adjoint of the pricing step. This allows one to compute the risk of portfolios of credit products faster than computing the portfolio value alone, thus making risk management in real time possible. Moreover on Friday 20 June 2014 he will give a mini-course on Real Time Risk Management with Adjoint Algorithmic Differentiaton The agenda is attached below. Interested people are invited to participate. For more information, contact Stefano Marmi (stefano.marmi(a)sns.it), Fabrizio Lillo (fabrizio.lillo(a)sns.it), or Giacomo Bormetti (giacomo.bormetti(a)sns.it). &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Friday June 20, Aula Bianchi, 11.00-12.30 Friday June 20, Aula Bianchi, 14.00-15.30 Adjoint Algorithmic Differentiation (AAD) is one of the principal innovations in risk management of the recent times. In this minicourse I will introduce AAD and show how it can be used to implement the calculation of price sensitivities in complete generality and with minimal analytical effort. The focus will be the application to Monte Carlo methods - generally the most challenging from the computational point of view. With several examples I will illustrate the workings of AAD and demonstrate how it can be straightforwardly implemented to reduce the computation time of the risk of any portfolio by order of magnitudes. 1.

ANNUNCIO DI SEMINARIO venerdì 13 giugno 2014, ore 14:30 Sala Bassini, Piano Rialzato CNR – IMATI, Via Bassini 15, Milano RELATORE Dr ZHUANG Jiancang Institute of Statistical Mathematics, Tokyo TITOLO Testing significance of earthquake precursors against earthquake clustering models instead of against complete randomness ABSTRACT During the last 30 years, a number of algorithms have been developed that search for seismic anomalies in order to predict strong earthquakes. Examples of such algorithms are M8, RTP, RTL, PI, and LURR. In these algorithms, behaviour is usually deemed to be anomalous if seismicity rates change from the background activity, which is usually assumed stationary or, more strongly, a Poisson process. On the other hand, it is well known that seismicity is clustered and can be well described by the Epidemic-Type Aftershock Sequence (ETAS) model. Such anomalies detected in these conventional ways may be caused by earthquake clusters or improper declustering algorithms. This presentation illustrates, through examples, how to modify these algorithms for the testing of seismic anomalies against a clustering model (e.g., the ETAS model). -- ------------------------------------------------------------------- Elisa Varini CNR - Consiglio Nazionale delle Ricerche IMATI - Istituto di Matematica Applicata e Tecnologie Informatiche via Bassini 15 - 20133 Milano (Italy) Tel +39 02 23699 527 Fax +39 02 23699 538 Email elisa(a)mi.imati.cnr.it -------------------------------------------------------------------

Si avvisa che in data 17-06-2014, alle ore 15:00 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatore: J. S. Marron Dept. of Statistics and Operations Research University of North Carolina Titolo: OODA of TreeStructured Data Objects Using Persistent Homology Abstract: The field of Object Oriented Data Analysis has made a lot of progress on the statistical analysis of the variation in populations of complex objects. A particularly challenging example of this type is populations of tree-structured objects. Deep challenges arise, whose solutions involve a marriage of ideas from statistics, geometry, and numerical analysis, because the space of trees is strongly non-Euclidean in nature. Here these challenges are addressed using the approach of persistent homologies from topological data analysis. The benefits of this data object representation are illustrated using a real data set, where each data point is the tree of blood arteries in one person's brain. Persistent homologies give much better results than those obtained in previous studies. Tutti gli interessati sono invitati a partecipare.

seminario di Luca Regis presso Prometeia - Bologna
by Giacomo Scandolo 09 Jun '14

09 Jun '14

Il giorno Giovedì 29 Maggio 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Luca REGIS (IMT Lucca) terrà un seminario dal titolo "Longevity risk modelling and hedging via continuous-time cohort models" Abstract Longevity risk, i.e. the risk of unexpected changes in the survivorship of policyholders, is perceived as one of the major threats to the long-run solvency of annuity providers, such as pension funds. Continuous-time models represent a useful tool in the modelling of stochastic mortality. Non-mean reverting affine cohort processes (Luciano and Vigna, 2008) provide a parsimonious but accurate description of mortality tables. They are particularly suited to pricing and hedging purposes, due to their analytical tractability. I present applications of such models to the management of insurance portfolios. I focus on longevity risk hedging techniques, such as natural hedging, and reinsurance strategies. I will discuss the implementation and the effectiveness of such strategies, as well as the effects of different risk sources (interest-rate risk, investment risk) - along with longevity risk - on the solvency of insurers.

Seminario di Fabrizio Leisen a RM1
by Fabio Spizzichino 03 Jun '14

03 Jun '14

ll Prof. Fabrizio Leisen (Univ. of Kent, Canterbury, UK) terrà, presso il Dipartimento di Matematica dell'Universita' La Sapienza, un seminario dal titolo Dependent Vectors of Random Probability Measures Mercoledi' 4 giugno, Ore 14:30, Aula E Le persone interessate sono invitate a partecipare Abstract: The definition of vectors of dependent random probability measures is a topic of interest in applications to Bayesian statistics. Indeed, they can be used for identifying the de Finetti mixing measure in the representation of the law of a partially exchangeable array of random elements taking values in a separable and complete metric space. In this talk we describe the construction of vectors of random probability measures based on the normalization of an exchangeable vector of completely random measures that are jointly infinitely divisible. The dependence can be achieved in many ways and in this talk will be shown some recent constructions based on Levy Copulas or the stick breaking representation. Finally, the dependence structure of the vectors is studied through some quantities of interest. This talk is a review of papers in collaboration with Antonio Lijoi, Federico Bassetti, Roberto Casarin, Weixuan Zhu and Dario Spano.
