主 题:Efficiency. Preliminary test Regression-type estimator
摘 要:If data on an auxiliary variable X correlated with the variable Y under study are available, regression-type estimators are often used to estimate the population mean mu[sub y]. An estimator based on a preliminary, test of significance that chooses between the difference estimator and the regression estimator has been proposed. This article investigates the efficiency of the proposed regression-type estimator with respect to other regression-type estimators. [ABSTRACT FROM AUTHOR]
