Program Specifications
LIMDEP AND NLOGIT are written for use on Windows driven microcomputers. LIMDEP and NLOGIT are generally compatible with Windows 95 and later Windows operating systems. For Windows Vista, the Help systems used by LIMDEP and NLOGIT are no longer installed as standard in Windows Vista, and Microsoft has released an update. (See FAQ for details.)
The programs require 16 megabytes of memory and occupy approximately 10 megabytes on the local hard disk drive.
