Software

Zelig

Zelig is a single, easy-to-use program that can estimate, help interpret, and present the results of a large range of statistical methods. It literally is "everyone's statistical software" because Zelig uses (R) code from many researchers. We also hope it will become "everyone's statistical software" for applications, and we have designed it so that anyone can use it or add their methods to it.

ZeligChoice

ZeligChoice adds several choice regressions - ordinal, multinomial and bivariate - to Zelig.

ZeligGAM

ZeligGAM adds general additive models to Zelig.

ZeligMultilevel

This package adds multilevel (a.k.a. hierarchical or mixed-effect) models to Zelig.

ZeligNetwork

ZeligNetwork adds social-network regressions to Zelig.
