We consider the construction of perfect samplers for posterior distributions associated with mixtures of exponential families and conjugate priors, starting with a perfect slice sampler in the spirit of Mira and co-workers. The methods rely on a marginalization akin to Rao-Blackwellization and...

In univariate calibration, two standard estimators are usually opposed: the classical estimator and the inverse regression estimator. Controversies have followed the use of both estimators and we consider them from a decision-theoretic perspective, establishing the inadmissibility of the...

The Monte Carlo programme used for the simulation of electron transport is based on a description of the samples by a layered model. The simulation accounts for the elastic scattering of electrons in selected materials and provides results to process the experimental data. In this paper, we...

This paper extends Besag's (1994) identifiability conditions to propose convergence conditions for the Gibbs sampler that are independent of the selected version of the conditional distributions. Moreover, we show that the support of the joint distribution must be connected if the Gibbs sampler...

Cet article presente les resultats d'une analyse comparative de 78 decisions rendues en 1992 et 1996 qui montre l'existence de differences dans le traitement des plaintes en matiere de discrimination en emploi par deux instances. Il souligne les implications de ces resultats pour les arbitres de...
