最优层界确定方法综述

A Overview of Approach on Determining the Optimal Strata Boundaries

回顾了分层抽样中层界最优解确定的解析方法和迭代方法,对比并评析了不同方法在计算繁杂程度、有效性等方面的优劣,针对偏态总体分层界限最优解的确定,对几何分层法提出了一种改进思路的变异系数法,并提出了进一步研究最优层界最优解确定方法的思路。

This paper reviews the analysics and iterative methods on determining tne optimal strata boundaries, comparing the difference methods on the degree and the effectiveness of the computation. This paper also gives a kind of improving method to advance the effectiveness on the geometric stratification. Finally this paper puts forward the future study path on determining the optimal strata boundaries.
