R and Rweb

R is an open source statistical software package: http://www.r-project.org/

R is used extensively by epidemiologists and geographers.

One can download R (free): http://cran.cnr.berkeley.edu/

The base install of R can be extended with R packages.
A fairly comprehensive list of R packages is here: http://cran.r-project.org/web/packages/

The R software is level III approved for use at the CDC.

The R software runs on your desktop but the R code can be run through a web service.

An example of an R web service is RWeb: http://www.math.montana.edu/Rweb/

Specific packages such as EpiTools have been developed by UC Berkeley and they support full epidemiology coursework with R.

If you have questions or wish to see this in action...just stop by;
