Vlad Stefan Barbu Laboratory of Mathematics Raphaël Salem, University of Rouen – Normandy, France Hypothesis testing based on weighted divergences Abstract : In this presentation, we first focus on a class of hypothesis tests for assessing the goodness-of-fit of a distribution, as well as on a class of homogeneity tests between two samples, in an iid framework.

  Xavier Milhaud Associate Professor at the university Aix-Marseille (Institute of mathematics) Impact of heat waves on mortality: extension of parametric longevity models to account for global warming Abstract : Global warming significantly impacts human health, with intense heat waves causing spikes in mortality, particularly among the elderly.

Thomas Nagler LMU Munich The surprising effect of reshuffling the data during hyperparameter tuning Abstract : Tuning parameter selection is crucial for optimizing predictive power of statistical and machine learning models models.

The latest forecasting innovations, showing how data can be transformed into valuable predictive insights Note: This talk will be given in presence in room C-115.  Online access is possible but the quality cannot be guaranteed. Speaker: Thomas Christ, Chief data scientist at the company prognostica, Würzburg, Germany. Summary: In today’s fast-paced world, data-driven forecasting is cruc

Sébastien Laurent IAE Aix-Marseille Asymptotics for penalized QMLEs of time series regressions We examine a linear regression model applied to the components of a time series, aiming to identify time-varying, constant as well as zero conditional beta coefficients. To address the non-identifiability of parameters when a conditional beta is constant, we employ a lasso-type estimator.

  Communicating about Statistics Speakers: Christian Ritter and Laura Symul, UCLouvain Summary:  In this seminar, we will discuss how to communicate efficiently about statistics via graphics, tabulation, presentation, and writing. In the first half, from 14h30 to 15h30, we will focus on visual communication through graphics and tables.

  Quentin Guibert Maître de conférence à Paris-Dauphine (CEREMADE) An extrapolation of temperature effects based on time series data in France Abstract : Most contemporary mortality models rely on extrapolating trends or past events. However, population dynamics will be significantly impacted by climate change, notably the influence of temperatures on mortality.
