In this article we discuss three estimators for population ratio using the coefficien regression and dual, which is a review from the article of Onyeka et.al [GlobalJournal of Science Frontier Research, 13(2013):57-65]. The three estimators are biased estimators and their mean square errorsare determined. Furthermore, this mean square errorsare compared to mean square error of each estimator.This comparison shows that thetype-product estimator is more efficient than another estimators.
