This study addresses the estimation problems of modified Lindley distribution using a progressive Type-II censoring plan. Using maximum likelihood and product spacing Bayesian methods, unknown parameter, reliability, hazard rate functions are estimated. Employing assumption gamma prior symmetric loss function, Bayes estimators investigated when observed data obtained functions. Additionally, ap...

This paper discusses the design of the optimal SSALT plan using Bayesian approach and progressive Type-I right censoring for an exponential life distribution under large sample size and small censoring proportion. The cumulative exposure model and the exponential life distribution in both steps are assumed. The progressive Type-I right censoring can reduce the cost of the test. This reduction, ...

In this paper we compute the expected Fisher information and the asymptotic variance-covariance matrix of the ML estimates based on progressively Type-II censored sample from Weibull distribution by direct calculation as well as the missing information principle. These values are then used to determine the optimal progressive censoring plans. Three optimality criteria are considered and some se...
