What to do when you want to understand disease spread over a social network… but you can’t actually observe the network?
NIASRA member Dr. Krivitsky has recently published a paper in Annals of Applied Statistics describing an approach for fitting whole-network models to egocentrically-sampled data: data where the researchers can only observe limited information about a small sample of individuals and non-identifying information about their partners. This facilitates simulation of what the whole network might look like, and how it might mediate the spread of disease.
