22 p, 459.3 KB Modelling multivariate, overdispersed count data with correlated and non-normal heterogeneity effects / Kazemi, Iraj (University of Isfahan (Iran). Department of Statistics) ; Hassanzadeh, Fatemeh (University of Khansar (Iran). Department of Statistics)
Mixed Poisson models are most relevant to the analysis of longitudinal count data in various disciplines. A conventional specification of such models relies on the normality of unobserved heterogeneity effects. [...]

10 p, 87.7 KB A note on the likelihood and moments of the skew-normal distribution / Martínez, Eliseo H. (Universidad de Antofagasta) ; Varela, Héctor (Universidad de Antofagasta) ; Gómez, Héctor W. (Universidad de Atacama (Chile)) ; Bolfarine, Heleno (Universidad de Sao Paulo)
In this paper an alternative approach to the one in Henze (1986) is proposed for deriving the odd moments of the skew-normal distribution considered in Azzalini (1985). The approach is based on a Pascal type triangle, which seems to greatly simplify moments computation. [...]
