Exponentiated Weibull Distribution on Censored Data in Clinical Trial

Abstract

Recent studies in clinical trial, Weibull distribution play an important role because simulation studies indicated that, Weibull distribution is less biased than other distribution in maximum likelihood. It estimators in small samples are less biased as compared other forms of imputations. In this paper, Weibull distribution was applied to clinical censored data. The result indicated that, Weibull distribution is comparatively has less biased estimators, small variance and smaller confidence interval than mean imputation techniques.
