No variables specified for an SSCP matrix. Execution terminating warning. Please help!

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!, ,

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;
