Estimation of Generalized Inverted Exponential Distribution based on Adaptive Type-II Progressive Censoring Data
In this paper, we consider generalized inverted exponential (GIE) model. Three issues represent the purpose of this paper. First, based on adaptive progressively Type-II censored data, we derive the maximum likelihood estimators (MLE) of the model parameters as well as the reliability and hazard rate functions. Next, the Bayes estimates are evaluated by applying Markov chain Monte Carlo method under ... Read more

Estimation of R = P(Y < X) using k-Upper Record Values from Kumaraswamy Distribution
The problem of estimating the stress-strength R = P(Y < X) when X and Y are two independent ordinary samples was considered by many authors. In this paper, the problem of estimation of R = P(Y < X) when X and Y are two independent k-upper record values from the Kumaraswamy distribution is considered. Maximum likelihood (ML) and Bayes techniques ... Read more

Bayesian Estimation from Exponentiated Frechet Model using MCMC Approach based on Progressive Type-II Censoring Data
Based on progressively Type-II censored samples, the maximum likelihood (ML) and Bayes estimators for the parameters as well as some lifetime parameters (reliability and hazard functions) of the exponentiated Frchet (EF) distribution are derived. The confidence interval of the parameters are obtained based on an asymptotic distribution of maximum likelihood estimators. Further; we consider delta method and bootstrap method to ... Read more

Assessing the lifetime performance Index using exponentiated Frechet distribution with the progressive first-failure-censoring scheme
Process capability analysis has been widely used to monitor the performance of industrial processes. In practice, lifetime performance index is a popular means to assess the performance and potential of their processes, where L is the lower specification limit. This study constructs the maximum likelihood (ML) and the Bayesian estimators of C_ for the exponentiated Frechet (EF) model with progressive ... Read more
