WebJan 1, 2024 · Exponential-family random graph models (ERGMs) are one of the most popular tools used by social scientists to understand social networks and test hypotheses about these networks ( Robins et al., 2007, Holland and Leinhardt, 1981, Frank and Strauss, 1986, Wasserman and Pattison, 1996, Snijders et al., 2006, and others). WebDec 3, 2024 · We employ ERGMs on the patent citation network to study the effect of various self-defined covariates on the patent citation forming mechanisms. We posit that since the patent network is a large network consisting of several nodes and edges, ERGMs will be able to estimate parameters effectively.

WebJan 15, 2024 · Exponential random graph models (ERGM) is a family of statistical distributions for ties in a social network. The inferential goal is to explain the mechanisms of tie-formation in networks such as why some people collaborate and others don’t. WebERGM is increasingly recognized as one of the central approaches in analyzing social networks (Lusher et al., 2012, Robins et al., 2007, Wang et al., 2013). ERGMs account for the presence (and absence) of network links and thus provide a model for unidimensional bipartite multidimensional 5 analyzing and predicting network structures.
