Resumen de On stochastic comparisons of finite mixtures for some semiparametric families of distributions

Nil Kamal Hazra, Maxim Finkelstein

• In this paper, we consider the classical finite mixture model, which is an effective tool for modeling lifetime distributions for random samples from heterogeneous populations. We discuss new results on stochastic comparison for two finite mixtures when each of them is drawn from one of the following semiparametric families, i.e., proportional hazards, accelerated lifetime and proportional reversed hazards
