Consistency of the Gmlewith Mixed Case Interval - Censored

In this paper we consider an interval censorship model in which the end-points of the censoring intervals are determined by a two stage experiment. In the rst stage the value k of a random integer is selected; in the second stage the endpoints are determined by a case k interval censorship model. We prove the strong consistency in the L 1 ()-topology of the nonparametric maximum likelihood estimate of the underlying survival function for a measure which is derived from the distributions of the endpoints. This consistency result yields strong consistency for the topologies of weak convergence, pointwise convergence and uniform convergence under additional assumptions. These results improve and generalize existing ones in the literature.
