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. Webfitting ERGMs may preclude their use with very large networks (e.g., voxel-based networks with tens of thousands of nodes) and certain combinations of network measures. Here we illustrate the utility of ERGMs for modeling, analyzing, and simulating complex whole-brain network. We also provide a
