- In this paper, we apply two-stage sampling which is not only commonly used in survey sampling but also has great advantages over element and cluster sampling. These advantages are comprehensively described in some sampling literature. Thus, we examine two-stage ratio-cum-product estimators with unequal sub-sampling fractions and obtain their MSE equations. The optimum sampling and sub-sampling fractions were also derived for these estimators. It is shown theoretically that these two-stage estimators will be more efficient than Singh (1965, 1967) estimators if certain conditions are satisfied. Finally, a numerical illustration with discussions is carried out to show the application of this technique. (original abstract)
