Re-release of 1993 AHEAD (Final, Version 2.10): Distribution Files Reformatted

February 4, 2003

The 1993 distribution files have been re-released as .zip files instead of .exe files.

The data files have been re-released in our standard format -- ASCII data (.DA) files and associated program statement files for SAS, SPSS and Stata users. This will facilitate usage by analysts using SPSS and Stata as formerly the 1993 data files were available only as SAS internal and SAS transport files. In addition:

The contents of most of the documentation files have not changed. The codebook documentation and questionnaire are now distributed only in Adobe .PDF format.

You'll typically want to download the ASCII data files, and one set of program statement files, and questionnaire and documentation (codebook) files. See the revised readme21 and Changes2003 for more details.
