Seminario Daniela Bertacchi - Politecnico di Milano - 20 Giugno 2024
by Luca Scarpa 17 Jun '24

17 Jun '24

Si segnala il seguente seminario a tutti gli interessati. Giovedì 20 Giugno 2024, ore 11. Aula Seminari Mox VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Daniela Bertacchi, Università di Milano-Bicocca. Title: A new stochastic order applied to branching random walks. Abstract: Stochastic ordering is a powerful tool to compare random variables and processes. We introduce a new type of stochastic ordering which generalizes the germ order introduced by Hutchcroft in 2022, which uses the generating function of the process. We apply this order to compare different branching random walks on a countable space $X$. We prove that given two branching random walks with law $\mu$ and $\nu$ respectively, with $\mu\ge\nu$, then in every set where there is extinction according to $\mu$, there is extinction also according to $\nu$. Moreover, in every set where there is strong local survival according to $\nu$, there is strong local survival also according to $\mu$, provided that the supremum of the global extinction probabilities, for the $\nu$-process, taken over all starting points $x$, is strictly smaller than 1. New conditions for survival and strong survival for inhomogeneous branching random walks are provided. We also extend a result of Moyal (1962), on the properties of fixed points of the generating function of a branching random walk.

Ricevo e inoltro volentieri. G From: Andrea Ghiglietti <andrea.ghiglietti(a)unimib.it> Date: Friday, 14 June 2024 at 11:52 To: Giacomo Aletti <giacomo.aletti(a)unimi.it> Subject: Seminar Prof. William F Rosenberger @unimib Dear all, you are invited to participate to the following seminar on Tuesday 25th of June 2024 at 11:00 at University of Milano-Bicocca (Via Bicocca degli Arcimboldi 8 - Milano - Room 2062, Building U7, 2nd floor): Speaker: William F. Rosenberger (George Mason University) Title: Casual Inference for Clinical Trails*: A Spellchecker’s Guide to Randomization Tests in Complex Settings Sir Austin Bradford Hill, the developer of the first randomized clinical trial, was a proponent of simplicity in statistical analysis, and strongly emphasized careful study design as the critical component of all medical studies. While he didn’t mention randomization tests in his 1937 book, I believe he would have liked their simplicity and interpretability. Any inference procedure which assumes random sampling from a population ignores Fisherian principles regarding the analysis of designed experiments. And clinical trials are the quintessential designed experiment. While we hear quite often about preservation of type I error rates and, more recently, about causal inference, these are natural elements of a randomization test. We discuss these issues and demonstrate that randomization tests can be used for more complex settings, such as multiple (>2) treatment comparisons, analyses with missing outcome data, and subgroup analyses. It is interesting to note that the only cohort of statisticians NOT excited about randomization tests in this age of causal inference are the designers and conductors of randomized clinical trials! I will conclude with a few historical notes about Fisher and de Finetti*. *The two most often misspelled words during my term as Biometrics co-editor.
