Irène Gijbels, Department of Mathematics, University of Leuven (KU Leuven), Belgium, terrà il seminario:
*Measures of asymmetry for multivariate distributions*
*Abstract* - In univariate settings the notion of measuring skewness of a distribution is well established. Extending this to measuring skewness (or asymmetry) in a multivariate setting is less obvious. In this talk we start by briefly reviewing some notions of asymmetry measures. We next propose a novel functional asymmetry measure (index) which is based on the natural idea of reflective symmetry around the mode. The proposed index is extended to the multivariate setting and a summarizing scalar (or vector based index in multivariate settings) is derived from it. Some illustrative examples are provided, and estimation of the proposed asymmetry index is discussed in parametric and nonparametric (multivariate) settings.
Il seminario si svolgerà presso la sede *CNR-IAC di Napoli*, *sala conferenze “Vaccaro”*, in modalità mista: in presenza e in streaming al link *https://www.youtube.com/watch?v=eEPimm1_aww https://www.youtube.com/watch?v=eEPimm1_aww*
Si ricorda che i seminari del ciclo si terranno di *martedì alle 14:30*, *a settimane alterne*, *salvo eccezioni* a partire da martedì 14 gennaio 2025.
