A common type of reliability data is the right censored time-to-failure data. In this article, we developed a control chart to monitor the time-to-failure data in the presence of right censoring using weighted rank tests. On the basis of the asymptotic properties of the rank statistics, we derived the generic formulae for the operating characteristic functions of the control chart to show the r...

Comparative lifetime tests are extremely significant when the experimenters study reliability of comparative advantages two products in competition. Considering joint type-II censoring, we deal with inference product lines conform to Gumbel distributions. The maximum likelihood estimations population parameters were obtained current research. An approximate confidence interval and a simultaneou...

For a sequence of independent and identically distributed random vectorsXi = (X1 i , X2 i , . . . , X i ), i = 1, 2, . . . , n, we consider the conditional ordering of these random vectors with respect to the magnitudes of N(Xi ), i = 1, 2, . . . , n, where N is a p-variate continuous function defined on the support set of X1 and satisfying certain regularity conditions. We also consider the Pr...

Constant-stress procedure based on parametric lifetime distribution and model is often used for accelerated life testing in product reliability experiment. Maximum likelihood estimation is the typically statistical inference method. This paper presents a new inference method, named random variable transformation (RVT) method for Weibull constant-stress accelerated life test with progressively T...

1: In this paper we discuss measures of information and divergence and model selection criteria. Three classes of measures, Fisher-type, divergencetype and entropy-type measures, are discussed and their properties are presented. Information through censoring and truncation is presented and model selection criteria are investigated including the Akaike Information Criterion (AIC) and the Diverge...
