----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Giovedì 8 Ottobre, ore 10,30 ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche "Sapienza" Università di Roma Prof. D. De Canditiis (CNR-IAC) Titolo: *Stima della densità dell'intensità di dati Poisson* Sintesi: Motivati dall'analisi di dati astronomici di tipo conteggio si presenterà un metodo per la stima della f.d.p. (funzione densità di probabiltà) della intensità di dati di tipo Poisson. La necessità di dare all'intensità un carattere stocastico nasce dall'esigenza di modellizzare una extra-variabilità contenuta nei dati. Le difficoltà della stima della f.d.p. sono assimilabili a quelle della soluzione (numerica) di un problema inverso lineare mal-posto. La soluzione, intesa come uno stimatore della f.d.p, ha ottime proprietà di convergenza. La metodologia verrà presentata in termini generali e dunque può essere presa come spunto per la risoluzione di altri problemi di analisi dati anche non necessariamente di tipo conteggio. Tutti gli interessati sono invitati a partecipare. Cordiali saluti Alessandro De Gregorio

CHRISTIAN HENNIG - Quantile-based classifiers - 6.10.15 ore 12.30 - Dipartimento di Statistica e Metodi Quantitativi - Bicocca Milano

Dipartimento di Statistica e Metodi Quantitativi Martedì 6 ottobre 2015 ore 12.30 U7/2104 (AULA ECONOMICA) II PIANO Quantile-based classifiers with application to the classification of bioaerosols CHRISTIAN HENNIG Senior Lecturer, Department of Statistical Science, University College London Abstract Quantile classifiers are generalisations of the median-based classifiers recently introduced by Hall et al. (2009). They work for potentially high-dimensional data, and are defined by classi- fying an observation according to a sum of appropriately weighted component-wise distances of the components of the observation to the within-class quantiles. The optimal quantiles can be chosen by minimizing the misclassification error in the training sample. I will present some theory and simulations results demonstrating that quantile classifiers are very competitive. Quantile classifiers will also be applied to the detection of bioaerosol particles based on gaseous plasma electrochemistry (Sarantaridis et al., 2012). As several other classifiers, quantile classifiers aggregate information coming from the indivi- dual variables. This depends on selection and standardisation of the variables. I will discuss the- se issues in a way that may hopefully be of more general statistical interest. The first aspect is the extraction of some meaningful features from the high-dimensional and quite redundant ori- ginal form of the bioaerosol data. The second aspect is to understand standardisation as va- riable weighting, including the option to refrain from standardisation in situations where the variability of variables may be roughly proportional to the variable importance for classification, or to standardise certain groups of variables against each other, as will be suggested for the bioaerosol data.

Seminario Prof. Mesiar a RM1

Il Prof. Radko Mesiar (STU Bratislava) terrà un seminario sul tema *On the role of ultramodularity (and Schur concavity) in the construction of binary copulas* Il prossimo Venerdì 2 ottobre, ore 14:30, presso l'Aula di Consiglio del Dipartimento di Matematica dell'Universita' La Sapienza Tutte le persone interessate sono invitate ad intervenire Fabio Spizzichino *Abstract. * We discuss and stress the role of ultramodularity in special types of constructions of binary copulas. After recalling of some known ultamodularity-based results, we focus on a the so-called D-product of a copula and its dual. We show that for each copula D which is ultramodular and Schur concave on the left upper triangle of the unit square, this D-product of an arbitrary copula and its dual is again a copula. Several examples and counterexamples are given. Finally, some of our results are generalized to the case of semicopulas and quasi-copulas. Work in collaboration with E. P. Klement, A. Kolesarova and S. Saminger-Platz

Dear all, in collaboration with Evry University, ENSIIE and University Paris Diderot, the Department of Mathematics of the University of Padova is organizing a Winter School on recent advances in Mathematical Finance, that will be held in Padova in the period *8-12 February 2016*. Two main courses, on “Energy Markets” and “Pricing with Funding and Counterparty Risks” will be given, respectively, by Rene Aid (EdF) and Andrea Pallavicini (Banca IMI and Imperial College). Moreover, four mini-course are scheduled, on longevity risk (Nicole El Karoui), optimal stopping (Goran Peskir), polynomial processes (Martin Larsson) and numerical methods (Nadia Oudjane). More details can be found at the link: http://www.maths.univ-evry.fr/conferences/padova2016/index_ws.htm#section1 Accomodation during the period 7-12 February will provided to a limited number (maximum 35) of students selected among candidates who will send us, via the online form available here: http://www.maths.univ-evry.fr/conferences/padova2016/Application_ws.htm#sec… their CV and recommendation letter before the *31st October 2015.* Thanks for your attention and see you in Padova!

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Veberdi 2 Ottobre 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Frederic LAVANCIER (Université de Nantes) DETERMINANTAL POINT PROCESS MODELS AND STATISTICAL INFERENCE Abstract: In this talk, I will demonstrate that Determinantal point processes (DPPs) provide useful models for the description of repulsive spatial point processes. Such data are usually modeled by Gibbs point processes, where the likelihood and moment expressions are intractable and simulations are time consuming. I will recall the definition of a DPP and review some of these appealing properties which make DPP models well suited for statistical analysis. In particular the ’most repulsive’ DPP will be characterized. Parametric models of DPPs will be introduced, where the likelihood and moment expressions can be easily evaluated and realizations can be quickly simulated. Some illustrations on real datasets will be presented. This work has been carried out in collaboration with Jesper Møller and Ege Rubak, Aalborg University. The study of the repulsiveness of DPPs is part of a joint work with Christophe Biscio, University of Nantes. 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
