Con preghiera di massima diffusione a tutti i potenziali interessati. *** Nell'ambito del Progetto di Partenariato Esteso GRINS è appena stata bandita una posizione RTD-A nel settore SECS-S/01 sul tema Statistical Learning per il progetto GRINS - Growing Resilient, INclusive and Sustainable Scadenza: 13-02-23 Dettagli della procedura: bando<https://www.polimi.it/personale-docente/lavorare-al-politecnico/bandi-e-con…> L’attività di ricerca verterà sullo sviluppo di modelli statistici per la previsione ex-ante e la valutazione ex-post dell'impatto degli investimenti in infrastrutture e servizi per migliorare l'accessibilità, la resilienza e la sostenibilità dei territori e delle città (WP2 Progetto GRINS – PNRR PE9 Spoke7). Sarà necessario comprendere come i fattori tangibili (infrastrutture e infostrutture) interagiscono con quelli intangibili (coesione e inclusione sociali, mobilità,…) per definire la sostenibilità di un territorio e a) identificare gli elementi funzionali a rendere i territori accessibili; b) individuare i gap territoriali e che limitano la sostenibilità e c) definire e valutare politiche per colmare tali gap. Sono richieste competenze avanzate di Statistical Learning e Analisi Dati, e comprovata conoscenza di Data Management e programmazione (R, Python). Il ruolo prevede lo svolgimento di attività didattica.

Seminario Prof. E. Ronchetti
by Enea Bongiorno 24 Jan '23

24 Jan '23

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 31 gennaio ore 16.30 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Title: *An Introduction to Saddlepoint Approximations* *Prof. Elvezio Ronchetti* Research Center for Statistics and Geneva School of Economics and Management University of Geneva, Switzerland Elvezio.Ronchetti(a)unige.ch www.unige.ch/gsem/en/research/faculty/honorary-professors/elvezio-ronchetti/ Abstract: Classical inference in statistics is typically carried out by means of standard (first-order) asymptotic theory. However, the asymptotic distribution of estimators and test statistics can provide a poor approximation of tail areas especially when the sample size is moderate to small. This can lead to inaccurate p-values and confidence intervals. Several techniques, both parametric and nonparametric, have been devised to improve first-order asymptotic approximations, including e.g. Edgeworth expansions, Bartlett's corrections, and bootstrap methods. Here we focus on saddlepoint techniques, introduced into statistics by H. Daniels, and more generally on small sample asymptotic techniques, an expression coined by F. Hampel to express the spirit of these methods. Indeed they provide very accurate approximations of tail probabilities down to small sample sizes and /or out in the tails. Moreover, these approximations exhibit a relative error of order 1/n, an improvement with respect to other available approximations obtained by means of Edgeworth expansions and similar techniques. We will review the basic ideas, show the link with other nonparametric methods such as empirical likelihood, and outline some connections to information theory and optimal transportation. ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1INut-6sD210FwZ437k3ydQA5P3xchdIr/view?usp=…> Seminari Matematici Statistici <https://sites.google.com/uniupo.it/seminari-ms/home-page> ----------------------------------- Tutti gli interessati sono invitati a partecipare.

Seminar Klopp @Bocconi
by Giacomo Zanella 23 Jan '23

23 Jan '23

We announce the following seminar (held only in person): 26/01/2023 at 12:00 Bocconi University, Via Roentgen 1, Milan Room 3-B3-sr01, floor 3 Speaker: Olga Klopp (ESSEC and CREST). Personal webapge: http://kloppolga.perso.math.cnrs.fr/ Title: Optimality of Variational Inference for Stochastic Block Model Abstract: Variational methods are extremely popular in the analysis of network data. Statistical guarantees obtained for these methods typically provide asymptotic normality for the problem of estimation of global model parameters under the stochastic block model. In the present work, we consider the case of networks with missing links that is important in application and show that the variational approximation to the maximum likelihood estimator converges at the minimax rate. This provides the first minimax optimal and tractable estimator for the problem of parameter estimation for the stochastic block model. We complement our results with numerical studies of simulated and real networks, which confirm the advantages of this estimator over current methods.
