Insights from Respondent Driven Sampling Datasets Via Complex Network Analysis

Abstract (Summary)

This research applies network theory to the Sexual Acquisition and Transmission of HIV Cooperative Agreement Program (SATHCAP) dataset to determine unique and/or shared attributes of important nodes within three US cities: Chicago, Los Angeles, and Raleigh-Durham. We generate large forests of nodes representing successful chains of recruitment for each city, then attempt to identify valuable nodes. We use betweenness centrality as a metric for a nodes importance, valuing the bridging qualities of high-betweenness nodes. After identifying these high-betweenness nodes, we find attributes that distinguish these nodes from the underlying population, presenting both the shared exceptional attributes between the high-betweenness nodes and the unique exceptional attributes within the high betweenness nodes. By assessing these exceptional attributes, we are able to draw conclusions about several key biomarkers that represent prime candidates for a targeted intervention program to slow the spread of an HIV pandemic.
