In many of the studies concerning Accelerated life testing (ALT), the log linear function between life and stress which is just a simple re-parameterization of the original parameter of the life distribution is used to obtain the estimates of original parameters but from the statistical point of view, it is preferable to work with the original parameters instead of developing inferences for the...

In this paper, the well-known proportional hazards model which includes several well-known lifetime distributions such as exponential,Pareto, Lomax, Burr type XII, and so on is considered. With both Bayesian and non-Bayesian approaches , we consider the estimation of parameters of interest based on progressively Type-II right censored samples. The Bayes estimates are obtained based on symmetric...

We obtain explicit expressions for single and product moments of the order statistics an omega distribution. also discuss seven methods to estimate parameters. Various simulation results are performed compare performance proposed estimators. Furthermore, maximum likelihood method is adopted parameters under type II censoring scheme. The usefulness distribution proven using a real data set.

Abstract Various types of censoring schemes basically type-I and type-II their modified versions are used in life testing experiments. Most the tests experiments based on a single sample. A joint scheme is quite useful conducting comparative products from different units within same facility. In this article, we consider two exponential time models under multiply scheme, which generalization us...
