重权数在复杂调查的方差估计中的应用

The Application of Replicate Weight in the Complex Survey

方差估计是抽样调查的重要组成部分,重抽样方法是常用的方差估计方法。重权数方法与重抽样方法类似,也是利用计算机的优势通过重复获得大量不同的子样本的重权数估计目标参数的估计量和方差估计量,是一种稳健、通用、有效的方差估计方法。本文主要介绍重权数在复杂抽样调查的方差计算中的理论和应用。

The variance estimation is very important part in sample survey,and replicated sample method is a common method.Replicate weight,which is similar with replicated sample method,gets a lot of replicated weights to obtain the estimators by computer,it is also a robust,common and effective method.This paper expatiates that how to use this method in complex survey.
