“Estimating Population Size with Adaptive Sampling in Hard-to-Reach Populations”

Date: Thursday, October 9, 2014

Hard-to-reach populations are typically not covered by a sampling frame thereby making recruitment a difficult task. Consequently, conventional methods of sampling can lead to unreliable estimators of population quantities. Instead, adaptive (link-tracing) sampling can be used to study such populations as social links of individuals can be exploited to adaptively select units for the sample. An abundance of literature on estimation of population quantities exists for when the population size is known. However, strategies that can be used to study populations when the size is unknown have yet to be adequately explored. In this talk two adaptive sampling-based strategies for estimating the size and attributes of hard-to-reach populations are presented. The first strategy is based on a model-based approach to inference and the second strategy is based on a design-based approach to inference. Simulation results from applying the two strategies to an empirical data set based on a drug-using population at risk for HIV/AIDS is presented.
