Statistical inference for a hybrid systemmodel with incomplete observed data under adaptive progressive hybrid censoring

摘要

In this article, the statistical inference of a hybrid system with incomplete observed data is studied based on the adaptive type-II progressive hybrid censored samples. It is assumed that the lifetime of the component in hybrid systems follows an identical Weibull distribution. The maximum likelihood estimates of the unknown parameters and reliability function are obtained by using the fixed-point iteration method. Under general entropy loss function, the Bayesian estimates and the highest posterior density credible intervals of the unknown parameters and reliability function are derived using Markov Chain Monte Carlo method. In addition, the approximate confidence intervals and Bootstrap confidence intervals are constructed. Finally, Monte Carlo simulation study is carried out to illustrate the performances of two different point estimates and different confidence intervals.
