Nlogit 6.0

NLOGIT is a package of programs for analyzing data on multinomial choice. The program, itself, consists of a special set of estimation and analysis routines, specifically for this class of models and style of analysis. LIMDEP provides the foundation for NLOGIT, including the full set of tools used for setting up the data, such as importing data files, transforming variables (e.g., CREATE), and so on. NLOGIT is created by adding a set of capabilities to LIMDEP. The notes below describe this connection in a bit more detail.

NLOGIT 6 is a suite of programs for estimating discrete choice models that are built around the logit and multinomial logit form. This is a superset of LIMDEP’s models – NLOGIT 6 is all of LIMDEP 11 plus the set of tools and estimators described in this guide. LIMDEP 11 contains the CLOGIT command and the estimator for the ‘conditional logit’ (or multinomial logit) model.
CLOGIT is the same as the most basic form of the NLOGIT command described in Chapter N19.
The full set of features of LIMDEP 11 is part of this package. We assume that you will use the other parts of LIMDEP as part of your analysis. To use NLOGIT, you will need to be familiar with the LIMDEP platform.

At various points in your operation of the program, you will encounter LIMDEP, rather than NLOGIT as the program name, for example in certain menus, dialog boxes, window headers, diagnostics, and so on. Once again, these result from the fact that in obtaining NLOGIT, you have installed LIMDEP plus some additional capabilities.

If you are uncertain which program is actually installed on your computer, go to the About box in the main menu. It will clearly indicate which program you are operating.
