(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 ).

Seminario A. Bianchi a Modena

18 Nov '13

*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/

Ho il piacere di invitarvi al seguente seminario, che si terrà Martedi' 19 novembre 2013 alle ore 16:00 presso l'aula 1AD100 della torre Archimede via Trieste 63 Padova. 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.

SPEAKER: Prof. Alessandra Faggionato AFFILIATION: Dip. di Matematica, Roma La Sapienza TITLE: Flows, currents and symmetries for continuous time Markov chains: a large deviation approach. ABSTRACT: We consider a continuous time Markov chain on a countable space (finite or infinite). We focus on the large deviations of the empirical measure, flow and current, as well as their generalization to higher order. In several cases the associated rate function is explicit. As application we investigate the Gallavotti-Cohen functional and its symmetry, and discuss several systems, including birth-and-death Markov chains, random walks on lattices approximating diffusions under an external potential, particle systems. -- 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/

cari marco e francesco vi chiederei di far girare sulla mailing list random l'annuncio riportato sotto. grazie alessandra Martedi' 22 ottobre 2013, alle 14.30, nell'Aula B del Dip. di Matematica dell'Universita' La Sapienza, si terra' si seguente seminario Speaker: Pietro Caputo (Universita' di Roma III) Title: Large deviations in sparse random graphs: a local weak convergence approach Abstract: Consider the Erdos-Renyi random graph on n vertices where each edge is present independently with probability p = c/n, with c > 0 fixed. 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.

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.

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.

Nuovo server per la lista Random
by Marco Romito 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
