Exponential Random Graph Models: Theory and Applications on Historical Networks | Antonio Fiscarelli

Antonio Fiscarelli (Luxembourg Centre for Contemporary and Digital History) at the Conference HNR+ResHist2021 Conference "Historical Networks - Réseaux Historiques - Historische Netzwerke co-organised by HNR and ResHist.
About the workshop:
This workshop will provide an introduction to Exponential Random Graph Mod els (ERGMs), followed by some example applications on historical networks. ERGMs are a family of statistical models that help discover the processes underlying network formation [1-3]. They have been used extensively in social network analysis and are popular in various fields such as sociology [4, 5], ar chaeology [6], and history [7]. Within this framework, one can:
- Define a model for a network that includes covariates representing features like homophily, mutuality, triad effects, and a wide range of other structural features
- Obtain maximum-likehood estimates for the parameters of the specified model
- Test individual coefficients, assess models for convergence and goodness-of-fit - Simulate new networks from the underlying probability distribution implied by the fitted model
Prerequisites
- Basic concepts of statistics (mean, standard deviation, probability distribution)
- Basic concepts of network analysis (nodes, edges, degree, transitivity)
- Basic familiarity with R (network and sna packages)
