Estimation of stochastic actor-oriented models for the evolution of networks by generalized method of moments.

Journal de la Société Française de Statistique, 2015
The stochastic actor-oriented model (Snijders, Sociological Methodology, 2001) models the evolution of networks over time, given panel data in a fixed group of actors, where at each panel wave the network between these actors (a digraph structure) as well as attribute variables for these actors are observed.
