Abstract

‎Statistical prediction analysis plays an important role in various fields including medical and engineering sciences‎. ‎In this paper‎, ‎based on progressively Type-II right censored data‎, ‎we shall consider Bayesian two-sample prediction‎. ‎Generalized exponential (GE) model‎, ‎which has been introduced as a quite effective model for lifetime data analysis instead of the Weibull or gamma distributions‎, ‎is considered for obtaining prediction bounds for the s-th order statistic in a future random sample drawn independently and with different and arbitrary progressive censoring schemes. ‎ ‎Finally‎, ‎we carry out a simulation study to assess the computational comparison of coverage probabilities in different progressive Type-II censoring schemes based on Bayesian two-sample prediction‎. ‎In addition‎, ‎we present schemes which are .not suitable for predicting the s-th order statistic in a future random sample drawn from GE model
