I am trying to check t test while I have a variables dl dm dn (profit vs assets in 3 variations) while my class is az. The az is dummy variable with 0 or 1 (1 is a family and 0 is not a family).
This is my project:
proc ttest data=sasuser.sasfile120416;
var dl dm dn;
And the answer I got in log is
ERROR: The CLASS variable has more than two levels.
I checked and the az is only 1 and 0, so what it could be?
Thanks for any help!
