Abstract: We describe exponential random graph models, a family of statistical
models for social networks. New model specifications (Snijders, Pattison, Robins and Handcock, 2006) have greatly enhanced the capacity
of these models to fit observed network data. Simulation, estimation and
goodness of fit procedures will be discussed. An empirical example, dealing with the informal social structure of an all-male elite sporting club, illustrates the type of conclusions that may drawn using these models. We conclude with a brief review of our recent methodological
work, including parameter estimation based on incomplete network data
from snowball samples.
