The estimator of the population means for the proposed scheme as well as the bias and MSE were derived. The efficiency condition under which the modified estimator is more efficient than existing ones were also presented. Empirical study using four sets of populations was conducted and the results revealed that the proposed estimator was more efficientenEstimator; Population mean; Imputation scheme; Bias; Mean Squared Error (MSE)Article
