These materials will be useful in preparation for the NME workshop. We require at the least a working knowledge of the R programming language. If you are inclined, feel free to also browse through the Statnet tutorials and literature listed on this page.

## Software Installation

Please read the installation instructions linked below and have the software loaded before the workshop. This includes installing R and Rstudio.

It’s a good idea to have the most recent versions of all software installed – the course instructors will all be using current versions, and the code scripts provided in the course for you to run will assume this as well. This is especially true for the packages EpiModel and statnetWeb.

## R Tutorials

The NME workshop will depend on a good working knowledge of the R statistical software language, which is the basis of the statnet software for the analysis of network data. A good place to start is our R tutorial below.

## Statnet Tutorials

We encourage you to explore and practice your R skills with the tutorials for the statnet suite of software for the analysis of networks. You can find these tutorials HERE.

To guide discussion on the use of our network-based models, we recommend that you read the following two papers in Lancet HIV and the Journal of Infectious Diseases before the course. Because many of the methods are not included in the main papers, we suggest that you peruse the Supplementary Technical Appendices of at least one of the papers (you will see there is a good deal of overlap in the appendices between the two papers). In addition, you may be interested in skimming our primary methods paper on EpiModel in the Journal of Statistical Software.

### Other Literature

You may be also interested in reading papers on the statistical methods featured in this course and/or applications using these methods.

#### Applied Research using EpiModel (Epidemics and other diffusion processes)

EpiModel and its extension packages have been used in many scientific journal articles, in a wide array of fields. A list of these articles can be accessed in a wiki page or on Zotero.

A good current example is:
