摘要：
A class of estimators for estimating ratio and product of two finite population means in two-phase sampling is proposed. Asymptotic expressions for bias and mean squared error (MSE) are obtained. Asymptotic optimum estimators (AOEs) are also identified. An empirical study is carried out to illustrate the performances of the constructed estimator over usual estimator.
