To download, double click on the file of your choice. A pop-up window will allow you to save the file to a folder of your choice on your computer.


To save space and reduce transfer time, we have COMPRESSED all files. You will need to uncompress the files before you can work with them. We have compressed the files using the "zip" program. A commun unzip utility for Windows is WinZip, which you can download from the web. If you don't already have WinZip installed, follow this link to install WinZip on your computer:


Because most files have been compressed, their name extensions have changed. Below is a chart of the corresponding extension names for compressed and uncompressed files:

File Format
File name extension
SAS transport
SPSS portable

Note: In order to use SAS transport files, you need to change it to the SAS Windows or SAS Unix environment. In addition, if before you can use SPSS portable files, you need to change it to the extension .SAV
