Web24 Jan 2024 · Exponential random graph models (ERGMs) are a class of statistical model often used for modeling social networks [ 1, 2 ]. Parameter estimation in these models is a computationally difficult problem, and algorithms based on Markov chain Monte Carlo (MCMC) are generally used [ 2 – 10 ]. Webmodels, the graph are the data (i.e., we observe the network) and we want to make inference with this type of data (known as network data). 11.2 Undirected graphs A graphical model …
