Those of you familiar with SAS, how would I test for the multiple
regression assumptions?

To test the assumption in multiple regression is that the errors are
normally distributed, you would output the residuals from PROC REG
into a SAS data set using the OUTPUT statement in PROC REG.

Then you could test normality any one of a number of ways. You could
test it graphically by creating histograms in PROC GCHART, PROC
CAPABILITY or PROC UNIVARIATE. These last two procedures will also do
a formal test to see if the residuals are normally distributed.
