Introduction

The EpiModel package provides 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 temporal 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 API for extending these templates to address novel scientific research aims.

Documentation

This vignette provides a general orientation to the EpiModel tutorials and documentation within the package and hosted elsewhere online. Most full-length tutorials may be found at the EpiModel website (https://www.epimodel.org), which also points to our Network Modeling for Epidemics (NME) short-course (https://epimodel.github.io/sismid/).

The current version of EpiModel is v2.5.0. Within the package, you can consult the extensive help documentation and vignettes for each exported function:

help(package = "EpiModel")

To see the latest updates to EpiModel, consult the NEWS file in the package, which is also summarized on our Github Releases (https://github.com/EpiModel/EpiModel/releases).

If you are interested in the stochastic network model class, we suggest learning about using EpiModel with the following sequence:

  1. The best place to start is our primary main methods paper, published in the Journal of Statistical Software at the reference below.
  2. After that, we suggest you work through the Network Modeling for Epidemics course materials to understand some of the background network theory and see how to run parameterize and run built-in network models.
  3. Those interested in extending EpiModel for novel research aims should then consult the model extension materials of the NME course, and look at the variety of extension model templates in our EpiModel Gallery (https://github.com/EpiModel/EpiModel-Gallery).
  4. Some of the latest developments in EpiModel are related to working with network model inputs and outputs, which are covered in these advanced topics vignettes within the package:
