Disentangling homophily, community structure and triadic closure in networks. (arXiv:2101.02510v3 [cs.SI] UPDATED)

Network homophily, the tendency of similar nodes to be connected, and
transitivity, the tendency of two nodes being connected if they share a common
neighbor, are conflated properties in network analysis, since one mechanism can
drive the other. Here we present a generative model and corresponding inference
procedure that are capable of distinguishing between both mechanisms. Our
approach is based on a variation of the stochastic block model (SBM) with the
addition of triadic closure edges, and its inference can …
