Design and analysis of survival data under an integrated type-II interval censoring scheme.
This article considers the planning of Type-II interval censored life tests for exponentially distributed lifetimes. In particular, we explore two criteria that are based on the minimization of the asymptotic variance of maximum likelihood estimator of the model parameter and the associated cost of the experiment. A numerical study is conducted to evaluate the "optimal" plans based on these two criteria. The results of this study should provide practitioners useful insight in planning a Type-II interval censoring life test.
