Abstract |
|
|
| In this paper, progressive-stress accelerated life testing (ALT) is studied when the lifetime of test units follows power
generalized Weibull distribution (PGW). The maximum likelihood estimates (MLEs) and Bayes estimates (BEs) of the model
parameters are obtained under type-II progressive censoring. Moreover, the approximate and credible confidence intervals (CIs) of the
estimators are derived. Furthermore, a real dataset is analyzed to show the suggested methods. Also, simulation studies are conducted
to demonstrate the precision of the MLEs and BEs for the parameters of PGW distribution. Finally, some interesting conclusions are
obtained. |
