- is designed to estimate the parameters of a list of predetermined discrete choice models such as logit, binary probit, nested logit, cross-nested logit, multivariate extreme value models, discrete and continuous mixtures of multivariate extreme value models, models with nonlinear utility functions, models designed for panel data, and heteroscedastic models. It is based on a formal and simple language for model specification.
- is designed for general purpose parameteric models. The specification of the model and of the likelihood function is based on an extension of the python programming language. A series of discrete choice models are precoded for an easy use.
The software is developed in C++ and can be used on various platforms (Mac OS X, Linux, Windows). A web-based platform independent graphical user interface allows for an easy use of the software.
