We propose the weighted moments estimators (WMEs) of the location and scale parameters for the extreme value distribution based on the multiply type II censored sample. Simulated mean squared errors (MSEs) of best linear unbiased estimator (BLUE) and exact MSEs of WMEs are compared to study the behavior of different estimation methods. The results show the best estimator among the WMEs and BLUE...

We express our sincere thanks to the honorable Editors and anonymous Reviewers for valuable comments and fruitful suggestions, which significantly improved the manuscript. In this paper, hierarchical Bayes approach is presented for estimation and prediction of reliability indexes and remaining lifetimes of a cold standby series system under general progressive Type II censoring scheme. A simula...

background : diabetes mellitus is a metabolic disorder and is considered as the sixth most common cause of mortality. hospital readmission in patients with diabetes is important and can impose great costs on the health system. therefore, this study investigated factors affecting the readmission of patients with type ii diabetes to selected hospitals in kermanshah, iran, in 2012. methods: this w...

In this paper the geometric process is used for the analysis of accelerated life testing for MarshallOlkin Extended Exponential (MOEE) distribution using Type II censored data. Assuming that the lifetimes under increasing stress levels form a geometric process, The parameters are estimated by using the maximum likelihood method and the original parameters instead of the developing inference for...

This paper discusses step-stress partially accelerated life test under progressive type-II censoring with random removals. The removals from the test are assumed to have binomial distributions. The lifetimes of the test units are considered to be exponential distributed. The maximum likelihood procedure is followed to estimate the unknown parameters of the model. Optimum test plan is developed ...

Prediction on the basis of censored data is very important topic in many fields including medical and engineering sciences. In this paper, based on progressive Type-II right censoring scheme, we will discuss Bayesian two-sample prediction. A general form for lifetime model including some well known and useful models such as Weibull and Pareto is considered for obtaining prediction bounds as wel...
