Estimation dans un modèle de Koziol-Green généralisé

We consider a population where the lifetime X is informatively right-censored by a nonnegative r.v. Y, thus we obtain a r.v. Z=X∧Y. This r.v. Z is then noninformatively right-censored by a non-negative r.v. C. In a generalized Koziol-Green model, i.e. we assume that X and Y have proportional hazard functions, we introduce an estimator ΛˆX of the cumulative hazard function ΛX of X and we study its asymptotic properties.
