Probabilistic weighted Dirichlet process mixture with an application to stochastic volatility models

Canadian Journal of Statistics, Volume 53, Issue 2, June 2025.
Abstract In this article, we propose a flexible Bayesian modelling framework and investigate the probabilistic weighted Dirichlet process mixture (pWDPM). The construction and properties of a probabilistic weight function are illustrated. The advantage of the pWDPM under the log‐squared transformed stochastic volatility (SV) model is demonstrated.

Tuta absoluta's population genetic structure across Africa: Two well‐delineated but weakly differentiated groups suggesting few introductions and significant gene flow Structure génétique des populations de Tuta absoluta à travers l'Afrique: deux groupes bien délimités mais faiblement différenciés suggérent peu d'introductions et un flux génétique important

Agricultural and Forest Entomology, Volume 27, Issue 2, Page 223-240, May 2025.
Abstract Describing the genetic structure and diversity of invasive insect pest populations is essential to better understand a species' invasion history and success throughout its distribution range. Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) is a destructive pest of tomato and many other solanaceous crops, with very high economic impacts. Its
