EFFICIENT ESTIMATORS OF POPULATION MEAN USING AUXILIARY ATTRIBUTE IN STRATIFIED RANDOM SAMPLING

Abstract: This paper suggests new ratio estimators in stratified random sampling using the information of an auxiliary attribute. Theoretically, it is obtained the bias and mean square error (MSE) for these estimators and compare them with the MSE of classical combined ratio estimator. By these comparisons, it is demonstrated that proposed estimators are more efficient than the considered estimators. In addition, these theoretical results are supported with the aid of numerical examples. |
Keywords and phrases: ratio-type estimators, stratified random sampling, efficiency, mean square errors.
