Stata

Stata is your complete system for managing, graphing, and analyzing data. It is easy to learn through the extensive graphical interface yet completely programmable for the most demanding data management and statistical requirements. Stata also has a full matrix programming language (Mata). You have access to everything you need to script your analyses or even to create new Stata commands--commands that work just like those shipped with Stata. It is also extensible. You can easily search, add, and use any of the thousands of user-contributed commands. For more information, visit www.stata.com/stata14
