Abstract:
|
Zheng et al. (2006) present a new way to use overdispersion to estimate social network structures. We extend their analysis to allow model selections and adapt it to an interval-based data set. We compare our results to the results of a similar study. Besides estimating group and network sizes, we illustrate how social networks structures can be used to predict political opinions such as being in favor of a timetable for withdrawal from Iraq. T.
