Recent Information

There are now Matlab, S-PLUS, R and Console (command line) versions of BACC for both Linux/Unix and Windows. All versions of the software are available on the Software page. Documentation for all versions is available on the Documentation page.

An old Gauss version is available on request, but the Matlab, S-PLUS, and R versions are recommended. In the future, we plan to update the Gauss versions to take advantage of new features of Gauss.

Resources for those who want to develop new models for BACC are also available on request.

March 19, 2003: Files on website updated to correct known bugs in BACC 2003.

May 21, 2003: Problem with BACC for Matlab versions earlier than 6.5 is fixed.

June 3, 2003: Another problem with BACC for Matlab versions earlier than 6.5 is fixed. There are now separate versions of BACC for separate versions of Matlab.

BACC 2003 changes:



• A new regression model with autoregressive errors
• A new regression model with autoregressive errors, Markov discrete states and state dependent means
• A new Linux/Unix S-PLUS version
• A new Linux/Unix R version
• An improved Windows S-PLUS version
• An improved Windows R version
• Matlab versions now work with new version (6.5) of Matlab, as well as with older versions (5.0 and higher)
• Improved documentation
