seminario B. Huang

Lunedì 9 Maggio 2016 alle ore 14:00, presso l’Aula 1B1 dip. SBAI Università La Sapienza di Roma, si terra' il seguente seminario: SPEAKER: Bill Hsin-Hsiung Huang, Ph.D. (Dep. Of Statistics University of Central Florida) TITLE: An Affine-Invariant Bayesian Cluster Process with Split-Merge Gibbs Sampler ABSTRACT: We develop a clustering algorithm which does not requires knowing the number of clusters in advance. Furthermore, our clustering method is rotation-, scale- and translation-invariant coordinatewise. We call it “Affine-invariant Bayesian (AIB) process”. A highly efficient split-merge Gibbs sampling algorithm is proposed. Using the Ewens sampling distribution as prior of the partition and the profile residual likelihoods of the responses under three different covariance matrix structures, we obtain inferences in the form of a posterior distribution on partitions. The proposed split-merge MCMC algorithm successfully and efficiently estimate the partition. Our experimental results indicate that the AIB process outperforms other competing methods. In addition, the proposed algorithm is irreducible and aperiodic, so that the estimate is guaranteed to converge to the posterior distribution. Tutti gli interessati sono invitati a partecipare.

Salzburg Workshop on Dependence Models & Copulas (DMC-Salzburg, Austria)
by Durante Fabrizio 29 Apr '16

29 Apr '16

The Salzburg workshop on Dependence Models and Copulas will take place September 19-22, 2016, in Salzburg (Austria). The workshop features Irène Gijbels (Katholieke Universiteit Leuven, BE) Erich Peter Klement (JKU Linz, AT) Roger B. Nelsen (Lewis & Clark College, Portland, US) Ludger Rüschendorf (Albert-Ludwig-Universität Freiburg, DE) Matthias Scherer (Technische Universität München, DE) as plenary speakers and includes invited sessions organized by Axel Bücher (DE), Elena Di Bernardino (FR), Fabrizio Durante (IT), Maria Rita Iacó (FR), Piotr Jaworski (PL), Ostap Okhrin (DE), and Carlo Sempi (IT) as well as various promising contributed sessions. Aiming to provide a meeting point for researchers working in the field of Dependence Modeling and Copulas the workshop comprises both, contributions with a theoretical focus as well as contributions concentrating on applied aspects. In order to stimulate the discussion of new results, ideas and applications there will be no parallel sessions. Fees are kept at a minimum: 140 € for regular participants, 80 € for PhD Students registering before the end of May (including lunches, coffee breaks and conference dinner). Registration is open already, see www.dmc-salzburg.at/Fees_and_Registration.html<http://www.dmc-salzburg.at/Fees_and_Registration.html> for details - due to an unexpectedly high number of submitted contributions only a limited number of participants not giving a talk can register (first come first serve). All relevant info can be found on the workshop homepage http://www.dmc-salzburg.at We are looking forward to welcome you in Salzburg Fabrizio Durante & Wolfgang Trutschnig

Seminario VENTURA

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Venerdi 29 Aprile 2016 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Laura VENTURA (Università di Padova) ROBUST APPROXIMATE BAYESIAN INFERENCE The likelihood function is the basis of both frequentist and Bayesian methods. However, the stability of likelihood-based procedures requires strict adherence to the model assumptions: mild deviations from the model can lead to misleading inferential results. A possible Bayesian solution to robustness is to use a of robust pseudo likelihood, such as the quasi- and the empirical likelihoods, in the Bayes formula. However, in multiparameter problems the quasi-likelihood is cumbersome, while with small samples the empirical likelihood can be unstable. Moreover, some estimating functions can be difficult to evaluate, which rules out the use of the empirical likelihood and other existing methods (Bayesian bootstrap, Bayesian GMM, etc.). To avoid these drawbacks, in this contribution we focus on posterior distributions from robust unbiased M-estimating functions. These robust posteriors are obtained via Approximate Bayesian Computation (ABC) with the estimating functions used as summary statistics. Theory and examples with robust M-estimating functions are discussed. 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. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it
