PROC GAMSELECT

[NKormanik]

Has anyone gotten PROC GAMSELECT to work on a stand-alone PC SAS machine???

Error message:

5    /* Minimal PROC GAMSELECT test */

6    proc gamselect data=sashelp.class;

7        class sex;

8        model weight = spline(height) spline(age) / dist=normal;

9    run;

ERROR: The data set SASHELP.CLASS must use a CAS engine libref.

Since PROC GAMSELECT works with V9 datasets in standard SAS 9.4 (per SAS/STAT 13.1+ documentation), the CAS error suggests:

1. Installation Anomaly: Your SAS/STAT 15.2 might have a patch or corruption making PROC GAMSELECT think it’s in a Viya-like mode.
2. Procedure Misregistration: The procedure might be incorrectly registered to expect CAS, possibly due to a mixed installation or a failed update.
3. Undocumented Change: A TS1M7-specific quirk might have altered PROC GAMSELECT’s behavior, though this isn’t reflected in the official SAS 9.4 docs.

When I search the SAS doc it clearly states GAMSELECT is a Visual Statistics PROC only (available with Viya 3.5 or later) which requires a CAS engine:

There is a PROC GAM in SAS/STAT which you could try.

See also PROC GAMPL, which experts prefer to PROC GAM.

GAMSELECT is new in the 8.5 release of SAS Visual Statistics (which is a Viya product).

Frustrating and confusing that there are certain procedures included in PC SAS 9.4 m7 that do not function in that environment.  Regardless of whether one uses our own data or not.  When one tries them out the error message is received:

ERROR: The data set SASHELP.CLASS must use a CAS engine libref.

NOTE: The SAS System stopped processing this step because of errors.

Agree that PROC GAMPL looks promising.
