/* Dynamic Panel Model Based on Differenced Equations */

proc sort data=Cigar;
   by State Year;
run;

proc panel data=Cigar;
   id State Year;
   model LSales = LPrice LDisp LMin / dynsys;
run;

Hi, I want to run difference-GMM with my own data but first I want to understand with an example provided by SAS. I'm trying to replicate the SAS's example shown in https://documentation.sas.com/?docsetId=etsug&docsetTarget=etsug_panel_examples06.htm&docsetVersion=... However, the options DYNDIFF and DYNSYS are reported as not recognized. I am using SAS 9.4

Any ideas what's happening?

Hi,

I mean OLDER VERSION does not support DYNDIFF and DYNSYS, NEW VERSION support.

SAS ETS package start to support DYNDIFF and DYNSYS since SAS/ETS 14.3. You are using SAS/ETS 14.2.

Hi, 

The earlier release of SAS 9.4 (with SAS/ETS 13.1) does not support DYNDIFF and DYNSYS. It would be more helpful if you can provide the log file and I can tell which version it is.

Thanks, you mean the log file shown once I open SAS, if that so, here it is:

On the other hand, how do you know both before mentioned options are not available in SAS anymore, even though they still appearing on SAS's recently documentation.
