SAS Rountines
Below are links related to the sample data and the SAS routines. Data and SAS files are best used by right-clicking on the link and saving the files to your computer. SAS routines are posted here as text files (.txt), and can be opened and pasted into the SAS Editor. Alternatively, you can download the file, change its extension to .sas, and it should then open automatically in the SAS software.
