Gaussian representation of a class of Riesz probabilitydistributions
Abdelhamid Hassairi
The Wishart probability distribution on symmetricmatrices has been initially defined by mean of the multivariateGaussian distribution as an of the chi-square distribution. A morege…
Singular Riesz measures on symmetric cones
Abdelhamid Hassairi, Sallouha Lajmi
In this paper, we give an explicitdescription of a class of positive measures on symmetric conesdefined by their Laplace transforms in the framework of the Rieszintegrals. This wor…
Criteria of convergence of a non ordinary random continued fractions on a symmetric cone
Abdelhamid Hassairi
In this paper, we use a notion of ratio based on a division algorithm, to extend to a symmetric cone the definition of a continued fraction in its more general form. We then give a…
Beta-hypergeometric probability distribution on symmetric matrices
Abdelhamid Hassairi, Mouna Masmoudi
Some remarkable properties of the beta distribution are based on relations involving independence between beta random variables such that a parameter of one among them is the sum o…
Bayesian approach to cubic natural exponential families
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…
