Calcul de densites predictives dans le modele bayesien de Cox
Dirichlet a censures fixes
Article Ecrit par: Messaci, Fatiha ;
Résumé: This Note is devoted to the extension, to observations censored by constants, of the computation of predictive densities in the nonparametric Bayesian Cox:Dirichlet model, which has been developed for noncensored observations by N. Gouget and J. P. Raoult [N. Gouget, J.P. Raoult, Computation of predictive densities in the semi:parametric Bayesian Cox:Dirichlet model, Non Parametric Statistics 10 (1999) 307:341]. We compute the densities of restrictions to subsets of sides, i.e. the subsets characterized by fixing the censored variables and by setting equalities and strict inequalities between the noncensored observations.
