Weboverlap into a web of interwoven clusters. We refer to such interwoven dependency in dyadic data as “dyadic clustering.” By ignoring the dyadic clustering, the analysis would take the dyad-level changes emanating from a single leadership change as independently informative events, rather than a single, clustered event.
