Inference of R = P(Y < X) for two-parameter Rayleigh distribution based on progressively censored samples

摘要

The UMVUE and maximum likelihood estimator of R = P(Y X) for independent progressively Type-II censored samples from two-parameter Rayleigh distributions with different scale parameters are derived. Also the exact, asymptotic and bootstrap confidence intervals for R are evaluated. Using Gibbs sampling, the Bayes estimates and corresponding credible intervals for R are obtained. Applying Monte Carlo simulations, we compare the performances of the different estimation methods. Finally we use of two real data sets and show the competitive performance of the presented methods.
