How to convert d3.js SVG to PDF

Monday, January 30th, 2012

Consider the following plot:

The image above is an SVG created using d3.js. I am going to use it in a paper, so need to convert it to PDF. It so happened that how to do this is not common knowledge, as is mentioned in this blog (which is, by the way, a good and balanced source of information relevant to our profession). Here is a short tutorial on how to do it: (more…)

Does homophily exist?

Monday, May 9th, 2011

This spring I gave two talks, one at the New England Statistics Symposium (NESS) hosted by the Department of Statistics, University of Connecticut, and a post-qualifying talk in my home department. Both talks were on my work with my advisor Joe Blitzstein, and both drew heavily on the term homophily. The first talk concerned refined simulation study results concerning design-based estimation, and the second one was about model-based estimation under Respondent-Driven Sampling. For the latter, we consider the data collected within a recent study of populations at high risk of HIV conducted in San Diego. The study took nearly 2 years to complete and was aimed at collecting information describing behavioral and health aspects of the target population. It is a privilege and responsibility to be commissioned to analyze the collected data, as the results of the analysis may be used for subsequent policy decisions. Figure 1 demonstrates the (anonymized) recruitment trees of the study.

Networks with homophily, an interesting visualization

Tuesday, June 8th, 2010

The research I am currently involved in with my advisor Joe Blitzstein concerns networks with homophily. As per Wiki:

Homophily (i.e., love of the same) is the tendency of individuals to associate and bond with similar others. The presence of homophily has been discovered in a vast array of network studies. (more…)
