关于抽样调查中总体方差预先估计法的理论分析

A Theoretical Analysis on Prior Estimation of Variance in Sample Survey

主要讨论了在抽样设计中影响样本容量的重要因子———总体标准差的预先估计法 :“试点调查法”、“历史优选法”、“结构预测法”和“极值法” ,并详细阐述了这四种方法的应用原理和应用方法 。

This paper mainly deals with the key factor affecting sample sizes in sample design——prior Estimation Method of overall standard deviation,such as “pilot survey”,“history optimization”,“structure forecast”and “extremum method”.And this paper analyses in detail the application principles and methods of these four methods,and a theoretical basis of overall variance prior estimation is provided for sampling workers.
