Abstract:

This paper presented three estimators for the hazard rate function under the semi-parametric right random censoring model with some failure indicators missing at random. The strong consistency and asymptotic normality properties were studied. The numerical simulation indicates the proposed estimators are superior to the nonparametric estimators.
