Respondent-driven sampling (RDS) is a network sampling design which is widely and increasingly being used to study properties of individuals in a social network, e.g., HIV prevalance. Understanding and evaluating the estimators obtained through RDS depends heavily on understanding the process of who recruits whom, which in turn depends on homophily in the network. We propose a joint model for the underlying homophily and the RDS recruitment process, and demonstrate how it can be used in RDS estimation, especially in obtaining standard errors from a model-based perspective.
