On A New Method Of Bias Reduction: Alternative To Approximately Unbiased Ratio Estimators

Abstract

This paper proposes a new method of bias reduction from order n^-1 to order n^-2 resulting in a new approximately unbiased ratio estimator. The efficiency of this estimator for the ratio of population means of two characters is compared with the existing six other Ratio estimators under a linear regression model.
