I have the following proc reg statement, but for some reason, it gives me the "No variables specified for an SSCP matrix. Execution terminating."
Here is my proc reg statemen:
proc reg data = simdata_no_violations noprint outest = MyEst_no_violations;
by sim;
run;
I was wondering if it was my by statement, but I'm not sure. The sim variable is just the number of simulated dataset. And at the moment, I have 5 simulated datasets from the dataset.
Does anybody know why that warning occurs?
Thanks!, ,
You have no model statement.
In case others come here wondering. In my case I was receiving the same error after I had copied my code from a proc logistic step to a proc reg step. After deleting DESCENDING the code worked.
ORIGINAL SAS CODE:
Proc reg data=data_source DESCENDING;
model dependent = V1 V2 V3 V4;
TITLE "F";
run;
MODIFIED SAS CODE:
Proc reg data=data_source;
model dependent = V1 V2 V3 V4;
TITLE "F";
run;
