WebJul 1, 2024 · A central model for unipartite networks is the Exponential Random Graph Models (ERGM) introduced by Frank and Strauss (1986). This model class allows to explain local network structures, see Lusher et al. (2013). The ERGM has been extended in the last years to bipartite, aka two-mode network analysis.

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. WebIn the case of bipartite networks (sometimes called affiliation networks,) we can use ergm ’s terms for bipartite graphs to corroborate what we discussed here. For example, the …

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.
