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).
