在本文中，我们讨论使用辅助变量的补充信息来估计总体均值和总体均值比率的问题。根据两个参数，提出了两类估计器。每个涉及的估计量的偏差和均方误差均获得一阶近似。结果表明，通过正确选择参数值，估计器比传统估计器更有效。提供了数值示例。
In this paper we discuss the problem of estimating population means and ratios of population means using supplementary information on an auxiliary variable. Two classes of estimators are proposed, depending on two parameters. The bias and mean square error of each of the involved estimators is obtained to the first order of approximation. It is shown that, with a proper choice of the values for the parameters, the estimators are more efficient than the conventional estimators. Numerical examples are provided.
