PC Life Table Analysis System

NIOSH PC LTAS is an analytical software system for use in occupational cohort mortality studies. Here you can download the software and documentation, contact the developers, ask questions and add suggestions. We especially value your comments and criticisms, so please feel free to speak up.

The latest version, 1.0d was released in January 2001. Changes in version 1.0d fix errors in version 1.0d. Minor changes have also been made to the user manual. You are encouraged to download these new editions.

Work is now underway on a new incarnation of LTAS to run under Microsoft Windows (95, 98, ME, NT, 2000).  We invite suggestions from users of the DOS version.
