The Use of Predictive Modeling in the Evaluation of Technical Acquisition Performance Using Survival Analysis

Abstract

The cocept of ranked set sampling (RSS) is applicable whenever ranking on a set of sampling units can be done easily by a judgement method or based on an auxiliary variable. In this work, we consider a study variable Y correleted with auxiliary variable X which is used to rank thesampling units. Further(X,Y)is assumed to have Morgenstern type bivariate generalized uniform distribution. We obtain an unbiased estimator of a scale parameter associated with the study variable Y based on different RSS schemes and cesored RSS. Efficiency comparison study of these estimators is also performed and presented numericallly.
