差异补充、无回答和无补充对被试驱动抽样估计量的影响

The Effect of Differential Recruitment, Non-response and Non-recruitment on Estimators for Respondent-Driven Sampling

Amber Tomas, Krista J. Gile

摘要:

受访者驱动抽样是一种广泛使用的网络抽样技术,旨在从难以接触的人群中进行抽样。根据所得样本进行估计是一个活跃的研究领域,有软件可以计算人口比例的至少四个估计值。每一个估计量都声称解决了以前估计量的不足之处,但这些说法往往是没有根据的。在这项研究中,我们提供了一个基于模拟的比较现有的估计,集中在抽样条件,最近的估计是为了解决。我们发现没有估计一贯优于所有其他的,并强调抽样条件下,每个是首选的。

英文摘要:

Respondent-driven sampling is a widely-used network sampling technique, designed to sample from hard-to-reach populations. Estimation from the resulting samples is an area of active research, with software available to compute at least four estimators of a population proportion. Each estimator is claimed to address deficiencies in previous estimators, however those claims are often unsubstantiated. In this study we provide a simulation-based comparison of five existing estimators, focussing on sampling conditions which a recent estimator is designed to address. We find no estimator consistently out-performs all others, and highlight sampling conditions in which each is to be preferred.
