滚雪球抽样是一种非概率抽样方法,一般采用线索触发的方式进行抽样,即通过同伴推荐和再推荐来逐次抽取并组织样本。本文引入捕获再捕获抽样估计方法对并发多样本滚雪球抽样的总体规模进行估计,提出了以并发加权线性模型估计总体规模的基本思路,其中共权估计量方差最小、离散性质局部最优。最后,对一个真实的滚雪球抽样调查过程进行了实证分析。
滾雪毬抽樣是一種非概率抽樣方法,一般採用線索觸髮的方式進行抽樣,即通過同伴推薦和再推薦來逐次抽取併組織樣本。本文引入捕穫再捕穫抽樣估計方法對併髮多樣本滾雪毬抽樣的總體規模進行估計,提齣瞭以併髮加權線性模型估計總體規模的基本思路,其中共權估計量方差最小、離散性質跼部最優。最後,對一箇真實的滾雪毬抽樣調查過程進行瞭實證分析。

As one of non-probability sampling methods,Snowball sampling uses sampling methods by cues,which are triggered by peer recommendation and successive recommendation,to expansion tissue samples commonly. This paper introduces a sample estimation method called Capture-Recapture into the concurrent and diverse Snowball Sampling to estimate parameters. On the basis of comparing a variety of estimation methods including Peterson,Chapman and so on,this paper proposes a basic idea,that is,using a weighted linear model to estimate the overall size. And one empirical analysis of a real sample survey has been carried out.
