Tree Pólya Splitting distributions for multivariate count data

Samuel Valiquette, Jean Peyhardi, Éric Marchand +2

In this article, we develop a new class of multivariate distributions adapted for count data, called Tree Pólya Splitting. This class results from the combination of a univariate d…

Asymptotic tail properties of Poisson mixture distributions

Samuel Valiquette, Gwladys Toulemonde, Jean Peyhardi +2

Count data are omnipresent in many applied fields, often with overdispersion. With mixtures of Poisson distributions representing an elegant and appealing modelling strategy, we fo…

Choice of mixture Poisson models based on Extreme value theory

Samuel Valiquette, Frédéric Mortier, Jean Peyhardi +1

Count data are omnipresent in many applied fields, often with overdispersion due to an excess of zeroes or extreme values. With mixtures of Poisson distributions representing an el…
