Estimation and Prediction for the Inverse Weibull Distribution under an Adaptive Type-II Progressively Censored Data
In this article, we consider the problem of estimating some lifetime parameters based on adaptive progressive Type-II censored sample from the inverse Weibull distribution. Maximum likelihood (ML) and Bayesian approaches are used to estimate the unknown parameters, coefficient of variation, reliability and hazard functions. The Bayes estimators are obtained using both symmetric and asymmetric loss functions. However, the Bayes estimators ... إقراء المزيد

Step-Stress Partially Accelerated Life Tests Model in Estimation of Inverse Weibull Parameters under Progressive Type-II Censoring
In this paper, inverse Weibull (IW) distribution with the step-stress model and progressive type-II censoring data are considered. The maximum likelihood and Bayesian estimation are discussed for the distribution parameters and the acceleration factor. The outline criteria in Bayesian approach are settled under utilized non-informative and gamma informative priors under balanced squared error and balanced linear-exponential loss functions with the ... إقراء المزيد
