Modelling the Effect of Differential Recruitment on the Bias of Estimators for Respondent-Driven Sampling
نویسندگان
چکیده
Respondent Driven Sampling has previously been modelled as a random walk on a network. In this document we show that this model can be used to encompass within-group differential recruitment, and examine the implications for bias of several common estimators.

Sampling hidden populations is challenging due to the lack of convenience statistical frames. Since most populations exposed to special diseases are hidden and hard to reach, sampling methods that produce representative and efficient samples from the populations have become a study subject for researches all over the world. Because of the unknown probability of selecting samples in conventional...
متن کاملComparison of Respondent Driven Sampling Estimators to Determine HIV Prevalence and Population Characteristics among Men Who Have Sex with Men in Moscow, Russia
Analytically distinct estimators have been proposed for the calculation of population-based estimates derived from respondent-driven sampling (RDS), yet there have been few comparisons of the inferences from these estimators using empirical data. We compared estimates produced by unweighted analysis used to calculate sample proportions and by three available estimators that are used to calculat...
متن کاملRespondent-Driven Sampling: An Assessment of Current Methodology.
Respondent-Driven Sampling (RDS) employs a variant of a link-tracing network sampling strategy to collect data from hard-to-reach populations. By tracing the links in the underlying social network, the process exploits the social structure to expand the sample and reduce its dependence on the initial (convenience) sample.The current estimators of population averages make strong assumptions in o...
متن کاملA response to the use of respondent-driven sampling in urban Indigenous populations.
Critical review and evaluation of the article “Mental health and substance use in an urban First Nations population in Hamilton, Ontario” by Firestone et al. brought an important issue to the forefront, namely the use of respondent-driven sampling for participant recruitment. The use of respondent-driven sampling during the study’s recruitment period raises questions about the presence of any u...
متن کاملNew Survey Questions and Estimators for Network Clustering with Respondent-Driven Sampling Data
Respondent-driven sampling (RDS) is a popular method for sampling hard-to-survey populations that leverages social network connections through peer recruitment. While RDS is most frequently applied to estimate the prevalence of infections and risk behaviors of interest to public health, like HIV/AIDS or condom use, it is rarely used to draw inferences about the structural properties of social n...
