Avviso di seminario
by Cristina Zucca 04 Jul '14

04 Jul '14

A tutti gli interessati. Mercoledì 9 luglio 2014 alle ore 14.30 in AULA C (Palazzo Campana - Dip. di Matematica"G. Peano" - Univ. di Torino) il Prof. François Delarue (Université Nice Sophia-Antipolis) terrà un seminario dal titolo: The Landau Equation for Maxwellian molecules and the Brownian Motion on the group of rotations. Abstract: We show that the spatially homogeneous Landau equation for Maxwellian molecules can be represented through the product of two elementary stochastic processes. The first one is the Brownian motion on the group of rotations. The second one is, conditionally on the first one, a Gaussian process. Using this representation, we establish sharp multi-scale upper and lower bounds for the transition density of the Landau equation, the multi-scale structure depending on the shape of the support of the initial condition. -- Dr. Cristina Zucca Department of Mathematics University of Torino Via Carlo Alberto 10 10123 Torino, Italy tel: +39-011-6702850 fax: +39-011-6702878

Seminario DANIELS
by Matteo Ruggiero 27 Jun '14

27 Jun '14

**************************************************************** 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
by Luca di persio 26 Jun '14

26 Jun '14

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.
