WebERGM is increasingly recognized as one of the central approaches in analyzing social networks (Lusher et al., 2012, Robins et al., 2007, Wang et al., 2013). ERGMs account for the presence (and absence) of network links and thus provide a model for unidimensional bipartite multidimensional 5 analyzing and predicting network structures. WebERGMs are generative: Given a set of sufficient statistics on network structures and covariates of interest, we can generate networks that are consistent with any set of …
