Patent citation network analysis: A perspective from descriptive

WebERGMs represent the generative process of tie formation in networks with two basic types of processes namely dyadic dependence and dyadic independence. A dyad refers to a pair of nodes and the relations between them. Dyadic dependent processes are those in which the state of one dyad depends stochastically on the state of other dyads. 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.
