Statistical Software Resources
There are many statistical software packages available through the Social Science Computing Cooperative at UW-Madison (select "Statistical Software" and then "Submit" on the linked page to retrieve a comprehensive list). Some offer a version of "one stop shopping," others have very specific uses.
SAS, SPSS and Stata are three of the most comprehensive and popular packages. All offer extensive data manipulation and analysis capabilities. They all have considerable information available, including their own corporate web sites, voluminous printed documentation, and some of the other fine resources listed below.
