SUMMARY. In a life testing experiment (or a clinical trial), for staggering entry of units (including some batch arrival models), some nonparametric testing procedures (based on a general class of rank statistics and weighted empirical processes) under progressive censoring schemes are considered, for some multiple regression model. Adjustments needed to incorporate dropouts are also discussed....

In this paper, we are concerned with nonparametric estimation of the multivariate regression function in the presence of right censored data. More precisely, we propose a statistic that is shown to be asymptotically normally distributed under the additive assumption, and that could be used to test for additivity in the censored regression setting.

This paper considers inference under progressive type II censoring with a compound Rayleigh failure time distribution. The maximum likelihood (ML), and Bayes methods are used for estimating the unknown parameters as well as some lifetime parameters, namely reliability and hazard functions. We obtained Bayes estimators using the conjugate priors for two shape and scale parameters. When the two p...
