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.
