Post-doc position in Statistics at University of Padua
by Sara Pillan 25 Mar '22

25 Mar '22

The Department of Statistical Sciences of the University of Padua is advertising a Research Grant for PhD graduates or graduates with a master’s degree. The purpose of this research grant, with a duration of *12 months* and an amount of *Euro 25,930.00 gross*, is to carry out research activity into developing statistical models for high dimensional data following approaches both frequentist and Bayesian. Often a large number of quantitative, qualitative or mixed variables are available and in dealing with them in statistical models requires attention to computational and statistical problems such as the curse of dimensionality. In many cases objective methods are required, but in many fields, e.g., marketing, sociological or biomedical analysis, subjective or a priori information is available, which can be included in the modeling and estimation procedures. The complete call is available at https://www.stat.unipd.it/assegno-di-ricerca-di-tipo-resp-scientifico-prof-… The call will expire on April 8th, 2022. The application may only be submitted by completing the online procedure available at <https://pica.cineca.it/unipd/> https://pica.cineca.it/unipd/assegni-dipstat-4-2022/ Best regards, the administrative secretariat -- Ufficio Ricerca del Dipartimento di Scienze Statistiche Università degli Studi di Padova Via Cesare Battisti 241 - 35121 Padova tel. +39 049 8274125 / +39 049 8274167 www.stat.unipd.it

The method is based on the idea of deriving an approximate posterior density aiming to target the true (unavailable) posterior by running massive simulations from the model for different parameters to replace the intractable likelihood, choosing then those parameters whose simulations are good matches to the observed data. When applying ABC to stochastic models, the derivation of effective summary statistics and proper distances is particularly challenging, since simulations from the model under the same parameter configuration result in different output. Moreover, since exact simulation from complex stochastic models is rarely possible, reliable numerical methods need to be applied. In this talk, we show how to use the underlying structural properties of the model to construct specific ABC summaries that are less sensitive to the intrinsic stochasticity of the model, and the importance of adopting reliable property-preserving numerical (splitting) schemes for the synthetic data generation. Indeed, the commonly used Euler-Maruyama scheme may drastically fail even with very small stepsizes. The proposed approach is illustrated first on the stochastic FitzHugh-Nagumo model, and then on the broad class of partially observed Hamiltonian stochastic differential equations, in particular on the stochastic Jensen-and-Rit neural mass model, both with simulated and with real electroencephalography (EEG) data, for both one neural population [2] and a network of neural populations (ongoing work).

(PMS)^2 online talk: Luisa Andreis
by margherita Zanella 22 Mar '22

22 Mar '22

Dear colleagues, we are happy to announce the following online talk: Speaker: Luisa Andreis (Università di Firenze) Title: Phase transitions in random graphs and coagulation processes. Abstract: Inhomogeneous random graphs are a natural generalization of the well-known Erdos–Renyi random graph, where vertices are characterized by a typeand edges are present independently according to the type of the vertices thatthey are connecting. In the sparse regime, these graphs undergo a phase transition in terms of the emergence of a giant component exactly as the classical Erdos–Renyi model. We will present an alternative approach, via large deviations, to prove this phase transition. This allows a comparison with the gelationphase transition in coagulation processes and with phase transitions of condensation type emerging in several systems of interacting components. This is based on ongoing joint works with Wolfgang K\"onig (WIAS and TUBerlin), Tejas Iyer (WIAS), Heide Langhammer (WIAS), Elena Magnanini(WIAS) and Robert Patterson (WIAS). Date and time: Monday March 28, 17:30-18:30 (Rome time zone).
