Click here to go to the Zelig homepage. Zelig is a general purpose statistical package built on R, with a large and diverse array of methods from all theories of inference. All documentation follows the same style and mathematical notation so that if you understand one method, you'll be able to learn any other one easily. Zelig commands for all models involve the same simple three commands with the same syntax. Zelig marshals the power of R by harnessing the cacophony R's different styles, examples, syntax, documentation, and programming logic, all with a simple, command, and easy-to-use interface. It also adds value to existing models by providing tools to make them easy to interpret and present. Developers can add R packages to be run from Zelig by writing a few bridge functions.
