While most features of Zelig have remained unchanged, the original software
package has been divided into five distinct packages: Zelig, ZeligChoice,
ZeligGAM, ZeligMultilevel and ZeligNetwork. These packages correspond directly
to particular classes of statistical models: discrete choice models, general
additive models, multilevel models, and network regression models. All other
models from Zelig 3.5 remain in the main Zelig package.
