Tools for simulating mathematical models of infectious disease dynamics. Epidemic model classes include deterministic compartmental models, stochastic individual-contact models, and stochastic network models. Network models use the robust statistical methods of exponential-family random graph models (ERGMs) from the Statnet suite of software packages in R. Standard templates for epidemic modeling include SI, SIR, and SIS disease types. EpiModel features an easy API for extending these templates to address novel scientific research aims.

Documentation and Support
Website. The main website for EpiModel, with tutorials and other supporting files is http://epimodel.org/.
Methods Paper. A good place to start learning about EpiModel is the main methods paper published in the Journal of Statistical Software. It is available at http://doi.org/10.18637/jss.v084.i08.
Summer Course. Network Modeling for Epidemics is our annual 5-day course at the University of Washington where we teach the statistical theory, software tools, and applied modeling methods using EpiModel. Our course materials [LINK] are fully open-source and updated annually around the time of the course.
Email listserv. Users are encouraged to join the email list for EpiModel as a place to ask questions, report bugs, and tell us about your research using these tools.
The EpiModel Gallery
We recently started a new EpiModel Gallery that contains templates of extensions to EpiModel, for now focused on network-based mathematical models. We will be continuing to add new examples the gallery, and encourage users to either file requests for new examples or contribute them following our guidelines.
