Constant-Stress Partially Accelerated Life Testing for Weibull Inverted Exponential Distribution with Censored Data

Abstract

The novelty of this article is estimating the parameters of Weibull inverted exponential (WIE)
distribution with a constant stress partially accelerated life test (PALT) under adaptive type-II progressively
censored samples. Moreover, the maximum likelihood estimators (MLEs), their asymptotic variances confidence
intervals, and Bayes estimators (BEs) of the model parameters and the acceleration factor are obtained.
Furthermore, the approximate bootstrap and credible confidence intervals of the estimators are acquired. The
accuracy of the MLEs and BEs for the model parameters and the acceleration factor is investigated through the
simulation studies.
