Statistical Analysis of Exponential Lifetimes under an Adaptive Type-II Progressive Censoring Scheme
In this paper a mixture of Type-I censoring and Type-II progressive censoring schemes, called an adaptive Type-II progressive censoring scheme, is introduced for life testing or reliability experiments. For this censoring scheme, the effective sample size m is fixed in advance and the progressive censoring scheme is provided but the number of items progressively removed from the experiment upon...
متن کاملAdaptive Progressive Type-II Censoring
Extending the model of progressive Type-II censoring, an adaption process is introduced. It allows to choose the next censoring number taking into account both the previous censoring numbers and the previous failure times. After deriving some distributional results, it is shown that maximum likelihood estimators coincide with those in deterministic progressive Type-II censoring. Finally, infere...
متن کاملA Note on the Residual Lifetimes in a Life-test under Progressive Type-ii Right Censoring Scheme
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.
متن کاملPoint Prediction for the Proportional Hazards Family under Progressive Type-II Censoring
In this paper, we discuss dierent predictors of times to failure of units censored in multiple stages in a progressively censored sample from proportional hazard rate models. The maximum likelihood predictors, best unbiased predictors and conditional median predictors are considered. We also consider Bayesian point predictors for the times to failure of units. A numerical example and a Monte C...
متن کاملBayesian Estimation of the Exponential Parameter under a Multiply Type-II Censoring Scheme
This paper provides the estimation of the scale parameter of the exponential distribution under multiply type-II censoring. Using generalized non-informative prior and natural conjugate prior, Bayes estimator and approximate Bayes estimators of the scale parameter have been obtained under square error loss function. The proposed Bayes estimators and approximate Bayes estimators are compared wit...
