Technical Support Policy

We are frequently asked how to set up a particular model using LIMDEP and NLOGIT commands. Unfortunately, this question goes beyond technical support. We have thousands of users and, as much as we would like to, we cannot address general questions on econometric modeling or the translation of theoretical specifications to LIMDEP or NLOGIT commands.

For these types of questions, you might find the LIMDEP List Server helpful.

Technical support is only available for the current versions of our software, LIMDEP 11 and NLOGIT 6.
