Modeling the Visibility Distribution for Respondent-Driven Sampling with Application to Population Size Estimation

We develop a method for improved estimation of a participant’s inclusion probability based on their network size (degree) as well as other information.

Some New Models for Social Networks

This is the Keynote Address at the Australian Social Network Analysis Conference 2023. In it I discuss classes of exponential-family models that extend the range and realism of traditional classes.

Modeling of Networked Populations with Exponential-Family Random Network Models when data is Sampled or Missing

In this talk we discuss network modeling with a novel exponential-family class of models when the network in only partially observed.

Modeling of networked populations when data is sampled or missing

We discuss network modeling with a novel exponential-family class of models when the network has some stochastic covariates and is only partially observed.

Population Size Estimation Using Multiple Respondent-Driven Sampling Surveys

Respondent-driven sampling (RDS) is commonly used to study hard-to-reach populations since traditional methods are unable to efficiently survey members due to the typically highly stigmatized nature of the population. The number of people in these …

A Simulation-Based Framework for Assessing the Feasibility of Respondent-Driven Sampling for Estimating Characteristics in Populations of Lesbian, Gay and Bisexual Older Adults

Respondent-driven sampling (RDS) is a method for sampling from a target population by leveraging social connections. RDS is invaluable to the study of hard-to-reach populations. However, RDS is costly and can be infeasible. RDS is infeasible when …

Methods for Inference from Respondent-Driven Sampling Data

Respondent-driven sampling is a commonly used method for sampling from hard-to-reach human populations connected by an underlying social network of relations. Beginning with a convenience sample, participants pass coupons to invite their contacts to …

Evaluating Variance Estimators for Respondent‐Driven Sampling

Respondent-Driven Sampling (RDS) is a network-based method for sampling hard-to-reach populations that is widely used by public health agencies and researchers worldwide. Estimation of population characteristics from RDS data is challenging due to …

Removing Phase Transitions from Gibbs Measures

Gibbs measures are a fundamental class of distributions for the analysis of high dimensional data. Phase transitions, which are also known as degeneracy in the network science literature, are an emergent property of these models that well describe …

Network Model-Assisted Inference from Respondent-Driven Sampling Data

Respondent-driven sampling is a widely used method for sampling hard-to-reach human populations by link tracing over their social networks. Inference from such data requires specialized techniques because the sampling process is both partially beyond …
