Dynamic visualization of RDS version 2

Sunday, March 27th, 2011

Early this semester, I worked on complementing my visualization of the Respondent-Driven Sampling (RDS) process presented in this post to illustrate its evolution over time. That was how the second version was created, which is displayed here.

Please refer to the earlier post for detailed description of the main functionality. The second version implements an additional view of the process, which plots the portion of the underlying network as discovered by the RDS process over time. To switch to an alternate view at any time, press the change view button. The wide pink horizontal line in the alternate view marks the true population mean. (more…)

Model-based estimation for respondent-driven network sampling under homophily

Sunday, June 6th, 2010

On May 3 I gave a post-qualifying talk letting the department know how my research was going. It was for the work done in collaboration with my advisor Joe Blitzstein related to respondent-driven sapling (RDS). This is a process used to collect data from hard-to-reach populations, for example injection drug users or HIV infected people. RDS is ¬†used by public health agencies around the world and policy decisions are made with the results, so it is important to be able to carry out reasonable estimation with obtained data. (more…)
