Abstract

Recently Pal et al. introduced a mean estimator which generalized most of the known mean estimators. We introduce a class of estimators that performs better than Pal et al. estimator. Expressions for bias and MSE for the proposed estimator are derived up to first order of approximation. We use the six datasets for numerical comparison.

简单随机抽样中有限总体均值的改进一般类估计量

摘要

最近帕尔等人。引入了一个平均估计量,它概括了大多数已知的平均估计量。我们引入了一类比 Pal 等人表现更好的估计器。估计器。所提出的估计器的偏差和 MSE 的表达式被推导到一阶近似值。我们使用六个数据集进行数值比较。
