seminario di Gianni Pistone (DISMA-Politecnico di Torino)
by Paola Siri 14 Jun '23

14 Jun '23

Martedì 20 Giugno alle ore 11.00 presso l’aula seminari del DISMA (Politecnico di Torino) il prof. GIOVANNI PISTONE (de Castro Statistics, Collegio Carlo Alberto, e DISMA (former faculty)) terrà un seminario dal titolo Information Geometry of ANOVA and Transport Theory. ABSTRACT. Functional ANOVA (ANalysis Of VAriance) is used in Statistics and Sistem Theory. It is a non-parametric orthogonal splitting of the vector space of $L^2$ random variables. We use it to split the fibres of the affine statistical bundle. The base set consists of probability densities, and the fibres are vector spaces of Fisher’s scores. On a product sample space, one of the factors in the splitting is an additive model, while the other is a transport model. Tutti gli interessati sono invitati a partecipare. Per chi non avesse possibilità di partecipare in presenza, l'evento sarà trasmesso in streaming al seguente link https://didattica.polito.it/VClass/SeminarioPistone Paola Siri e Barbara Trivellato Paola Siri Probability, Statistics and Optimization group Department of Mathematical Sciences "G.

oggi ore 11.00 - Seminario Prof.ssa E. Rroji
by Enea Bongiorno 14 Jun '23

14 Jun '23

Buongiorno, con piacere segnalo il seguente seminario che si terrà oggi: -------------------------------- 14 giugno ore 11.00 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Title:* On the microstructure of green bonds* *Prof. Edit Rroji* University of Milano Bicocca - DISMEQ Abstract: The idea of this paper is to investigate differences in brown and green bonds from the lens of the trading activity. Our research exploits the idea that positive and negative jumps in the dynamics of returns have a specific memory nature that can be modelled through a self-exciting process. We investigate the microscopic structure and properties of high-frequency series of green and brown bonds using Hawkes type processes where the kernel is a CARMA(p,q) model. Empirical results suggest that the bid-ask spread of green bonds on average is larger for bonds issued by a financial institution while the opposite happens for bonds issued by a non financial company. Moreover, we observe that the intensities respectively of positive and negative jumps in the price dynamics are not stationary through time. Higher order bivariate Hawkes models provide better fitting results in our datasets, especially for the issuer that operates in the energy sector. This presentation is based on a joint work with Lorenzo Mercuri (University of Milan) and Andrea Perchiazzo (Vrije Universiteit Brussel). ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1NunY3uhobfzBtP0qUUbxLJpnqcvFn4JM/view?usp=…> Seminari Matematici Statistici <https://sites.google.com/uniupo.it/seminari-ms/home-page> ----------------------------------- Tutti gli interessati sono invitati a partecipare.

PMS^2 hybrid talk: Mario Maurelli - 21/06/2023 - Politecnico di Milano
by Margherita Zanella 13 Jun '23

13 Jun '23

Dear colleagues, we are happy to announce the hybrid - that is, in person with online streaming - talk of the (PMS)^2 series: Speaker: Mario Maurelli (Università di Pisa) Title: No blow-up by nonlinear It\^o noise for the Euler equations. Abstract: We consider the incompressible Euler equations in two or three dimensions and we show that the addition of a suitable multiplicative It\^o noise with superlinear growth prevents a smooth solution from blowing up in finite time. The result is valid for a more general hyperbolic-type SPDE. The proof is based on the Lyapunov function method. Joint work with Marco Bagnara and Fanhui Xu. Date and time: Wednesday June 21, 14:30-15:30 (Rome time zone). Place: Aula Seminari - III piano (third floor), Dipartimento di Matematica, Politecnico di Milano, Piazza Leonardo da Vinci, 32 – 20133 Milano - Ed. 14 “Nave” Campus Bonardi. (Accesso pedonale da: Via A.M. Ampère, 2 - Milano, Via E. Bonardi, 9 - Milano, Via G. Ponzio, 31 - Milano). Zoom link: https://polimi-it.zoom.us/j/95561910050?pwd=amJISEdSRnAxcW9pOU53ZDREaEZadz09 ID riunione: 955 6191 0050 Passcode: 455231 This is a talk of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia and Milano-Politecnico.

Next OWPS on June 21st: Maria Eulàlia Vares and Daniel Valesin
by Alberto Chiarini 13 Jun '23

13 Jun '23

OWPS's next session will be on Wednesday the 21st of June from 15:00 to 17:00 UTC (Coordinated Universal Time). We have the pleasure of introducing our next speakers: Maria Eulàlia Vares (Universidade Federal do Rio de Janeiro) and Daniel Valesin (University of Warwick) Title, abstract and the zoom link are below the signature and can be found on the website https://www.owprobability.org/one-world-probability-seminar. If you are interested in the project, we kindly ask you to share this announcement within your community. With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- Talk : Maria Eulàlia Vares and Daniel Valesin Title: Renewal contact process and contact process on dynamic random environments Abstract: In the first part of this talk, we will present recent progress on alternate versions of the Harris contact process, where we allow some aspect of the dynamics (transmissions or recoveries) to be governed by a general renewal process. In this case, several of the tools employed in the study of the classical process no longer apply, and new ones are required. We present conditions on the inter-arrival distribution of the renewal process that ensure survival or extinction of the infection. In the second part, we switch to a model introduced by Linker and Remenik (2020), namely the (classical) contact process evolving on a dynamical graph given by dynamic bond percolation on the edges of Z^d (the environment is thus defined by the percolation density p and the edge update rate v). Their work contains several interesting results about this model, including a result in dimension one that we extend to higher dimensions. This result states that, for any fixed value of the percolation density p below the critical threshold and the contact infection rate lambda, the infection dies out if the edge update rate v is small enough. Joint works with Luiz Renato Fontes (USP), Marcelo Hilário (UFMG), Domingos Marchetti (USP), Thomas Mountford (EPFL), Daniel Ungaretti (UFRJ).

Seminario di Sandra Cerrai al Politecnico di Milano
by Giuseppina Guatteri 13 Jun '23

13 Jun '23

Si avvisa che in data 22/06/2023, alle ore 15:30 precise, Aula Seminari III piano, dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative della sezione di Probabilità, si svolgerà il seguente seminario: An asymptotic approach to SPDEs on graphs Sandra Cerrai, University of Maryland Abstract: I will present some results about the asymptotic behavior of a class of stochastic reaction-diffusion-advection equations in the plane. I will show that as the divergence-free advection term becomes larger the solutions of such equations converge to the solution of a suitable stochastic PDE defined on the graph associated with the Hamiltonian. I will deal with the case when the stochastic perturbation is given by a singular spatially homogeneous Wiener process taking values in the space of Schwartz distributions. As in previous works, I will assume that the derivative of the period of the motion on the level sets of the Hamiltonian does not vanish. Time permitting, without assuming this condition on the derivative of the period, I will study a weaker type of convergence for the solutions of a suitable class of linear SPDEs. È gradita la sua partecipazione. Cordiali saluti.

Fwd: Seminario R.J. Little 13 giugno ore 10.30
by Brunero Liseo 12 Jun '23

12 Jun '23

Il giorno 13 giugno alle ore 10.30, Aula Di Fresco (quarto piano della facoltà di Economia Sapienza) Il prof. Roderick Little, University of Michigan, terrà un seminario dal titolo *Some Reflections on Rosenbaum and Rubin’s Propensity Score Paper* Tutti gli interessati sono invitati a partecipare. Il seminario è fruibile anche on line collegandosi alla pagina https://web.uniroma1.it/memotef/aule-e-laboratori-memotef-didattica e cliccando su *Link studente* in corrispondenza dell’*Aula di Fresco* *Abstract * Rosenbaum and Rubin’s paper is highly cited because the basic idea is simple and insightful, and it has applications to important practical problems in treatment comparisons with observational data, and selection bias and nonresponse in surveys. I discuss several issues related to the method, including the use of the propensity score for weighting or prediction, and two robust methods that use the propensity score as a covariate and can be more efficient than weighting when the weights are highly variable, namely Penalized Spline of Propensity Prediction (PSPP) and Penalized Spline of Propensity for Treatment Comparisons (PENCOMP). Approaches to addressing highly variable weights are discussed, including omitting variables in the propensity model that are unrelated to outcomes and redefining the estimand. -- ============================================ 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 *https://sites.google.com/a/uniroma1.it/brulis/home <https://sites.google.com/a/uniroma1.it/brulis/home>* ============================================ -- -- **Fai crescere le giovani ricercatrici e i giovani ricercatori* **con il 5 per mille alla Sapienza *Scrivi il codice fiscale dell'Università *80209930587 Cinque per mille <https://www.uniroma1.it/it/node/23149>*
