This study investigated progressive-stress ALT with progressive type II filtering with the lifetime of test units following a Nadarajah–Haghighi (NH) distribution. It is assumed that the scale parameter of the distribution obeys the inverse power law. The maximum likelihood estimates and estimated confidence intervals for the model parameters were obtained first. The Metropolis–Hastings (MH) algorithm was then used to build Bayes estimators for various squared error loss functions. We also computed the highest posterior density (HPD) credible ranges for the model parameters. Monte Carlo simulations were used to compare the outcomes of the various estimation methods proposed. Finally, one data set was analyzed for validation purposes.Attribution 4.0 United Stateshttps://creativecommons.org/licenses/by/4.0/Bayesian approachnon-Bayesian approachprogressive-stress modelinverse power lowNadarajah–Haghighi distributiontype II progressive censoringbalanced squared loss functionbalanced LINEX loss functionArticle2022-05-12
