A Note on the Residual Lifetimes in a Life-test under Progressive Type-ii Right Censoring Scheme
نویسندگان
چکیده
Suppose that n independent and identically distributed items have been placed in a life-test with Progressive Type-II censoring scheme (R1, R2, ..., Rm). In this paper, we investigate some characterizations and ordering results based on the residual lifetimes of the remaining items following the k failure in the test.

Inference for a Skew Normal Distribution Based on Progressively Type-II Censored Samples
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...
متن کاملModified Progressive Type-II Censoring Procedure in Life-Testing under the Weibull Model
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 ...
متن کاملSome Characterization Results on Generalized Pareto Distribution Based on Progressive Type-II Right Censoring
The progressive censoring scheme is a method of data collecting in reliability and life testing which has been of intensified interest in recent years. In the present paper, we prove some characterization results on generalized Pareto distribution based upon the independency and expected values of some functions of progressive type-II right censored order statistics.
متن کاملOptimal sample size and censoring scheme in progressively type II censoring based on Fisher information for the Pareto distribution
One of the most common censoring methods is the progressive type-II censoring. In this method of censoring, a total of $n$ units are placed on the test, and at the time of failure of each unit, some of the remaining units are randomly removed. This will continue to record $m$ failure times, where $m$ is a pre-determined value, and then the experiment ends. The problem of determining the optimal...
متن کاملBayesian Two-Sample Prediction with Progressively Type-II Censored Data for Some Lifetime Models
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 asWeibull and Pareto is considered for obtaining prediction bounds ...
