Statnet Workshop
Exponential Random Graph Models (ERGMs) using statnet

• Tutorial (HTML)
• Tutorial (PDF)
• Script with R commands from the tutorial

Prerequisites

Familiarity with R. If new to network analysis, the workshop Introduction to SNA with R and statnet is strongly suggested.

Description

This workshop provides a hands-on tutorial to using exponential-family random graph models (ERGMs) for statistical analysis of social networks, using the “ergm” package in statnet. The ergm package provides tools for the specification, estimation, assessment and simulation of ERGMs that incorporate the complex dependencies within networks. Topics covered in this workshop include:

• an overview of the ERGM framework;
• types of terms used in ERGMs
• defining and fitting models to empirical data;
  
• interpreting model coefficients;
  
• goodness-of-fit and model adequacy checking;
  
• simulation of networks using fitted ERG models;
  
• degeneracy assessment and avoidance.
