Abstract

In this article, we consider the estimation of population mean when some observations on the study characteristic are missing in the bivariate sample data. In all, five estimators are presented and their efficiency properties are discussed. One estimator arises from the the amputation of incomplete observations while the remaining four estimators are formulated using inputed values obtained by the ratio method of estimation.
