This article presents deviation based exponentially weighted moving average control charts to monitor type-I censored data. Due practical applications, this study considers Weibull distribution assess the performance of proposed memory-type charts. The observations are replaced with conditional expected value (CEV), median (CM), and standard (CSD) Various shifts, smoothing weights, censoring ra...

This paper considers optimal design problems for the Weibull distribution, which can be used to model symmetrical or asymmetrical data, in presence of progressive interval censoring life-testing experiments. Two robust approaches, Bayesian and minimax, are proposed deal with dependence D-optimality c-optimality on unknown parameters. Meanwhile, compound method is applied ensure a compromise bet...

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 ...

The Bayesian prediction of future failures from Lomax distribution is the subject this research. observed data censored using a Type-I hybrid censoring scheme under step-stress partially accelerated life test. There are two types sampling schemes considered: one-sample and two-sample. We create predictive intervals for failure observations in future. constructed MCMC algorithms. After all, nume...

In this paper, we insert and study a novel five-parameter extended Weibull distribution denominated as the Marshall–Olkin alpha power (MOAPEW) distribution. This distribution's statistical properties are discussed. Maximum likelihood estimations (MLE), maximum product spacing (MPS), Bayesian estimation for MOAPEW parameters obtained using Type I II censored samples. A numerical analysis Monte-C...

This paper describes a Bayesian method for optimum accelerated life test planning with one accelerating variable, when the acceleration model is linear in the parameters, based on censored data from a log-location-scale distribution. We use a Bayesian criterion based on estimation precision of a distribution quantile at a specified use condition and use this criterion to find optimum test plans...

This paper considers the three-parameter exponentiated Weibull family under type II censoring. It first graphically illustrates the shape property of the hazard function. Then, it proposes a simple algorithm for computing the maximum likelihood estimator and derives the Fisher information matrix. The latter one is represented through a single integral in terms of hazard function, hence it solve...
