I am trying to run forward selection on data deress2 :

proc reg data=assig.depress2;
model cesd=
age income education / selection=forward ;
run;

It gives me following error:

257 proc reg data=assig.depress2;
258 model cesd=
259 age income education / selection=forward ;
ERROR: Variable EDUCATION not found.
NOTE: The previous statement has been deleted.
260 run;

WARNING: No variables specified for an SSCP matrix. Execution terminating.
NOTE: PROCEDURE REG used (Total process time):
real time 0.01 seconds

Check your variable names. Run a proc contents and note the difference between the name and label.

The attached code shows the variable name to be EDUCAT. "Education" is the variable label, it is only used for display purposes.

The variable name is educat. Educatf is the format name. Attached code misses a semicolon after "proc reg data=assig.depress2"
