seminario Giovanni Puccetti in Bicocca
by Fabio Bellini 28 Nov '13

28 Nov '13

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).

Seminario CARON

**************************************************************** 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. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Avviso di mini-corso :: Varin@DSS (Scienze Statistiche, Sapienza)

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
