Seminario di Fisica Matematica e Probabilità Mercoledì 7 marzo, ore 16:15, Aula di Consiglio, Dipartimento di Matematica, Roma La Sapienza Speaker: Alessandra Occelli (Università di Bonn) *Title: On time correlations for last passage percolation models* Abstract. We study time correlations of last passage percolation (LPP), a model in the Kardar-Parisi-Zhang universality class, with three different geometries: step, flat and stationary. We prove the convergence of the covariances of the LPP at two different times to a limiting expression given in terms of Airy processes. Furthermore, we prove the behaviour of the covariances when the two times are close to each other, conjectured in a work of Ferrari and Spohn. -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

De Finetti Risk Seminar - February 2018
by Emanuela Rosazza 26 Feb '18

26 Feb '18

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Deciding with Judgment Simone Manganelli European Central Bank Abstract: Non sample information is hidden in frequentist statistics in the choice of the hypothesis to be tested and of the confidence level. Explicit treatment of these elements provides the connection between Bayesian and frequentist statistics. A frequentist decision maker starts from a judgmental decision and moves to the closest boundary of the confidence interval of the first order conditions, for a given loss function. This statistical decision rule does not perform worse than the judgmental decision with a probability equal to the confidence level. For any given prior, there is a mapping from the sample realization to the confidence level which makes Bayesian and frequentist decision rules equivalent. Frequentist decision rules can also be interpreted as decisions under ambiguity. LOCATION: The seminar will be held on Wednesday, February 28, at 18.00 at room 3-E4-SR03, Bocconi University, Via Rontgen 1, 3rd floor, Milano. A refreshment will be offered at 17.30.

seminar at LUISS
by Marco Scarsini 23 Feb '18

23 Feb '18

February 27 2018 from 12:00 to 13:00 LUISS room 104 viale Romania 32 00197 Roma Speaker: Dov Samet (Tel Aviv University) Title: Desirability Abstract: Savage's theory of decision shows the equivalence of two structures. One is the behavioral-observable preferences over acts, the other is the mental-unobservable structure of probability and utility. The latter is not only unobservable but also cannot be reported by the decision maker. We propose an alternative mental-unobservable structure of desirability preferences which can replace the pair probability-utility and can be consciously reported. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Seminari di Probabilità, Pavia: S. Boucheron e L. Dello Schiavo
by Federico Bassetti 22 Feb '18

22 Feb '18

Seminari di Probabilità, Pavia Mercoledì 28 Febbraio 2018 nell'aula Beltrami del Dipartimento di Matematica dell' Università di Pavia (via Ferrata 1) si svolgeranno due seminari: Ore 14.30: Stephane Boucheron, Univ. Paris Diderot "TBA" Ore 15.30: Lorenzo Dello Schiavo, Universität Bonn Characteristic functionals of Dirichlet measures and their algebraic properties Abstract: We consider Dirichlet—Ferguson (DF) measures, a family of random probabilities on a locally compact Polish space X. Introduced by T. S. Ferguson in Ann. Stat. 1(2) 209ff., 1973, these measures have ever since found applications widely ranging from Bayesian non-parametrics to population genetics and stochastic dynamics of infinite particle systems. We compute the characteristic functionals of DF measures relying on those of their finite-dimensional marginalizations, the Dirichlet (D) distributions on standard simplices. In finite dimensions, we identify the dynamical symmetry algebra L of the characteristic functional of D as a simple Lie algebra of type A. Additionally, we show that all integer semi-lattices of certain posterior D distributions have a natural structure of weight Lie algebra module for L. A probabilistic interpretation and a partial generalization of these results to the infinite-dimensional case of DF measures is at hand. If time permits, we will also address a second characterization of DF measures by means of a Georgii—Nguyen—Zessin-type formula (joint work with E. W. Lytvynov, Swansea University). Tutti gli interessati sono invitati a partecipare

Ca' Foscari University Seminars

21 Feb '18

Seminar Annoucement *********************************************************** Speaker: Aristidis K Nikoloulopoulos, School of Computing Sciences, University of East Anglia Title: Factor copula models for item response data Date: 28/02/2018, Hour: 11:00 Place: Meeting Room A - Zeta Building Dipartimento di Scienze Ambientali, Informatica e Statistica - DAIS Università Ca' Foscari - Venezia Edificio Zeta Via Torino, 155 I-30172 Mestre (VE) ITALY Abstract: Factor or conditional independence models based on copulas are proposed for multivariate discrete data such as item response. The factor copula models have interpretations of latent maxima/minima (in comparison with latent means) and can lead to more probability in the joint upper and/or lower tail compared with factor models based on the discretized multivariate normal distribution (or multidimensional normal ogive model). Details on maximum likelihood estimation of parameters for the factor copula model are given, as well as analysis of the behavior of the log-likelihood. Our general methodology is illustrated with several item response data sets and it is shown that there is a substantial improvement on existing models from the criteria of log-likelihood and goodness-of-fit. This talk will be based on collaborative work with Harry Joe (U. of British Columbia). -- Apologies for cross posting -- Carlo Gaetan -- Dipartimento di Scienze Ambientali, Informatica e Statistica - DAIS Università Ca' Foscari - Venezia Edificio Zeta Via Torino, 155 I-30172 Mestre (VE) ITALY phone: ++39 041 234 8404 mobile phone: ++39 366 629 7899 e-mail:[gaetan"at"unive"dot"it] web:[http://www.dais.unive.it/~gaetan] Please don't print this e-mail unless you really need to.
