statnet software was delivered on CDs (!) at the Social Networks Conference in Vancouver, BC in 2006, and the first two packages were published on CRAN in 2008 –
network (for data storage/management) and
ergm (for statistical analysis of network data using Exponential-family Random Graph Models).
Our software is still anchored by the
ergm packages, but has grown to a suite of 14 packages that extend the functionality of
statnet to a wide range of network data types and models (e.g., temporal, multi-level, valued tie, egocentrically sampled networks, etc.). Development is ongoing.
We maintain a large set of training materials online, see the “Workshops” tab above.
Who does all this work? Our development team and a cast of many contributing users over the years.
The Statnet Development Team
The core developers of the statnet packages have evolved over time, as has the package development process. We currently host our package development on GitHub, and accept contributions in the form of pull requests.
Our current lead developer/maintainer is Pavel Krivitsky.
