Description

tergm is a collection of extensions to the ergm package to fit, diagnose, and simulate models for dynamic networks — networks that evolve over time — based on exponential-family random graph models (ERGMs). For a list of functions type help(package='tergm')

When publishing results obtained using this package, please cite the original authors as described in citation(package="tergm").

Details

An exponential-family random graph model (ERGM) postulates an exponential family over the sample space of networks of interest, and ergm package implements a suite of tools for modeling single networks using ERGMs.

More recently, there has been a number of extensions of ERGMs to model evolution of networks, including the temporal ERGM (TERGM) of Hanneke et al. (2010) and the separable termporal ERGM (STERGM) of Krivitsky and Handcock (2013). The latter model allows familiar ERGM terms and statistics to be reused in a dynamic context, interpreted in terms of formation and dissolution of ties. Krivitsky (2012) suggested a method for fitting dyanmic models when only a cross-sectional network is available, provided some temporal information for it is available as well.

This package aims to implement these and other ERGM-based models for network evoluation. At this time, it implements, via the stergm function, the STERGMs, both a conditional MLE (CMLE) fitting to a series of networks and an Equilibrium Generalized Method of Moments Estimation (EGMME) for fitting to a single network with temporal information. For further development, see the referenced papers.
