Recently, progressive hybrid censoring schemes have become quite popular in a life-testing problem and reliability analysis. However, the limitation of the progressive hybrid censoring scheme is that it cannot be applied when few failures occur before time T . Therefore, a generalized progressive hybrid censoring scheme was introduced. In this paper, the estimation of the entropy of a two-param...

In many industrial experiments involving lifetimes of machines or units, experiments have to be terminated early or the number of experiments must be limited due to a variety of circumstances (e.g. when expensive, etc.) the samples that arise from such experiments are called censored data. Cohen (1991) was one of the earliest to study a more general censoring scheme called progressive censor...

This paper is concerned with the estimators problems of the generalized Weibull distribution based on Type-I hybrid progressive censoring scheme (Type-I PHCS) in the presence of competing risks when the cause of failure of each item is known. Maximum likelihood estimates and the corresponding Fisher information matrix are obtained. We generalized Kundu and Joarder [7] results in the case of the...

in this paper we introduce a new scheme of censoring and study it under the weibull distribution. this scheme is a mixture of progressive type ii censoring and self relocating design which was first introduced by srivastava [8]. we show the superiority of this censoring scheme (psrd) relative to the classical schemes with respect to “asymptotic variance”. comparisons are also made with respect ...

In many situations of survival and reliability test, the withdrawal units from test is pre-planned in order to free up testing facilities for other tests, or save cost time. It known that several risk factors (RiFs) compete immediate failure cause items. this paper, we derive an inference a competing risks model (CompRiM) with generalized type II progressive hybrid censoring scheme (GeTy2PrHCS)...
