Avviso di Seminario When September 8th 2016, 14:30 Where Sapienza Università di Roma facoltà di Economia Aula Fanfani, V piano Viale del Castro Laurenziano, 9 Speaker *Federico Camerlenghi* Università Luigi Bocconi, Milano Titolo *Distribution theory for hierarchical processes with statistical applications* Abstract In Bayesian nonparametrics, a large amount of literature has been carried out under the assumption that observations are exchangeable. However in a large variety of applications this may appear too restrictive, a typical example is when data are generated by different experiments: even if these experiments may be related, they have some specific features that induce heterogeneity across observations. In such a situation data are usually divided into different groups, and a more appropriate assumption is partial exchangeability. In particular the construction of dependent random probability measures to deal with partially exchangeable observations has recently attracted great attention in Bayesian nonparametric literature. In this talk we define and investigate general classes of nonparametric priors, namely hierarchical models, based on transformations of completely random measures. We are able to study all the analytical properties, i.e. the random partition structure, the predictive distributions and the posterior characterization of the processes. Finally some relevant applications to species sampling problems and survival analysis will be discussed. (This is a joint work with A. Lijoi, P. Orbanz and I. Prunster.) -- ============================================ Brunero Liseo *Dip. di metodi e modelli per il territorio, l'economia e la finanza * *Sapienza Università di Roma* *Viale Castro Laurenziano, 9 Roma I-00161 *Tel. +39 06 49766973 Fax +39 06 4957606 *http://www.memotef.uniroma1.it/users/liseo-brunero <http://www.memotef.uniroma1.it/users/liseo-brunero>* =============================================

seminario Steven Scott (Google) 2/9 in Bicocca
by fabio.bellini 30 Aug '16

30 Aug '16

Cari colleghi, vi segnalo che il giorno venerdì 2 settembre alle ore 17, presso la Aula Martini al piano interrato dell'edificio U6, Steven Scott, Director of Statistics Research at Google, terrà un seminario su Predicting the Present with Bayesian Structural Time Series This article describes a system for short term forecasting based on an ensemble prediction that averages over different combinations of predictors. The system combines a structural time series model for the target series with regression component capturing the contributions of contemporaneous search query data. A spike-and-slab prior on the regression coefficients induces sparsity, dramatically reducing the size of the regression problem. Our system averages over potential contributions from a very large set of models and gives easily digested reports of which coefficients are likely to be important. We illustrate with applications to initial claims for unemployment benefits and to retail sales. Although our exposition focuses on using search engine data to forecast economic time series, the underlying statistical methods can be applied to more general short term forecasting with large numbers of contemporaneous predictors (joint work with Hal Varian). L'evento è organizzato in collaborazione con Innovation Pub e sarà seguito da un piccolo rinfresco. Sarà inoltre possibile seguire lo streaming su http://streaming.unimib.it/.

Third StaTalk on Computational Tools for Statistical Modelling.
by Clara Grazian 29 Aug '16

29 Aug '16

Dear all, we are pleased to announce that the third meeting of the *StaTalk* series will be held at *Facoltà di Economia di Sapienza Università di Roma *on *September 9, 2016*. StaTalks are one-day workshops on statistical topics during which the hosting group introduces and overviews the main research interests of their members. Aimed at Master’s and PhD students, as well as at post-docs and young researchers, StaTalks are intended to be informal gatherings which allow for a more proficient interaction between presenters and participants. They typically feature some introductory tutorials on the main workshop theme and a few seminars that overview more advanced research topics, still kept at an expository level. StaTalks are thus a great opportunity to become acquainted with the workshop main topic, as well as to share and update one's knowledge on the interface of Statistical research in an easy and informal atmosphere. StaTalks are endorsed by Y-SIS ( https://sites.google.com/site/youngsocietaitalianastatistica/), the young section of the Italian Statistical Society. The topic of the third StaTalk will be on *Computational Tools for Statistical Modelling*. We will present and discuss both standard and new computational methods which represents fundamental tools for new challenging applications, such as economic, finance, genetic and official statistics. *Programme* *09.30-10.00 *Opening *10.00-10.40 *Christian Macaro (SAS System) "*A mixture of heterogeneous models with time dependent weights*" *10.40-11.10* Coffee break *11.10-11.50* Clara Grazian (MEMOTEF Department) "*Modelling financial dependence through approximate Bayesian inference*" *11.50-12.30* Stefano Vaccari (MEMOTEF Department) "*Pricing in the Presence of Social Learning: Modelling Information Aggregation in a Competitive Market*" *12.30-14.30* Lunch break *14.30-15.10 *Andrea Tancredi (MEMOTEF Department) "*A Bayesian approach for de-duplication, record linkage and inference with linked data.*" *15.10-15.50 *Luca Tardella (Department of Statistical Science) "*Alternative approaches for approximating marginal likelihood.*" *15.50-16.30* Davide Di Cecco (ISTAT) "*Towards the use of administrative sources in official statistics: Some examples of methodologies for administrative multi source integration utilized at ISTAT.*" *16.30-17.00 *Closing Additional info can be found at the workshop page https://sites.google.com/site/youngsocietaitalianastatistica/events/statalk… or by writing to clara.grazian(a)uniroma1.it. REGISTRATION to the third StaTalk is now open. *No conference fees are due, but registration is mandatory*, using the form available on the website.

Call for interest for two positions at the level of Associate Professor ============================================================= The Department of Mathematics of the University of Padova is seeking to fill two positions at the level of Associate Professor through direct appointment (Italian "chiamata diretta") or open competitive selection (Italian "concorso"). The call is open to scientists working in Mathematics or Computer Science. Candidates must be in possession of the Italian Scientific Qualification as Associate Professor ("abilitazione scientifica nazionale di seconda fascia") or hold a position equivalent to that of Italian Associate Professor at a foreign University or Research Institute. Candidates are asked to submit (at direzione(a)math.unipd.it) their CV and a letter of interest by 5th September 2016. Prospective candidates will be invited to the Department of Mathematics for a seminar talk and discussion with members of the Department. The Department plans to decide by the end of October 2016 whether to proceed with direct appointment or open competitive selection. In the case of open competitive selection a choice of the area (Italian "settore concorsuale) will be made and the selection is expected to take place in the first half of 2017.
