To … WebDec 3, 2024 · We employ ERGMs on the patent citation network to study the effect of various self-defined covariates on the patent citation forming mechanisms. We posit that since the patent network is a large network consisting of several nodes and edges, ERGMs will be able to estimate parameters effectively.

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.

WebAlthough ERGMs are easy to postulate, maximum likelihood estimation of parameters in these models is very difficult. In this article, we first review the method of maximum likelihood estimation using Markov chain Monte Carlo in the context of fitting linear ERGMs. 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.
