On some exact distributional results based on Type-I progressively hybrid censored data from exponential distributions

In this paper, we present an approach for deriving the exact distributions of the maximum likelihood estimators (MLEs) of location and scale parameters of a two-parameter exponential distribution when the data are Type-I progressively hybrid censored. In addition to this new result for the two-parameter exponential model, we also obtain much simpler expressions for those cases of Type-I hybrid censored data which have been studied before. Our …
