Abdelhamid Hassairi, Marwa Hamza
For a natural exponential family (NEF), one can associate in a natural way two standard families of conjugate priors, one on the natural parameter and the other on the mean paramet…

New characterizations of the Letac-Mora class of real cubic natural exponential families
Marwa Hamza, Abdelhamid Hassairi
In this paper, we give three equivalent properties of the class of multivariate simple cubic natural exponential families (NEF's). The first property says that the cumulant functio…
