Abstract
In this paper, we discuss the prediction problem of the lifetimes to failure of units from Rayleigh distribution with Type-II censoring for a simple step-stress setup under cumulative exposure model. We consider several methods of point prediction, including maximum likelihood predictor, conditional median predictor, and best unbiased predictor. In addition, we discuss the prediction intervals for future lifetimes of the censored units using pivotal quantity, highest conditional density, and shortest-length based methods. Monte Carlo simulation is conducted to compare the proposed prediction methods. Further, a real data set is analyzed for illustrative purposes.
