Dear Experts of SAS Support Community,


I have trouble: I am using SAS University Edition and would like to apply Proc Model for SUR to develop equations.

My code is below :


proc model data=AllData;
parms a1=0.6122 b1=0.7692 c1=0.3694
a2=0.6122 b2=0.7692;

AGB = a1*(DBH2HWD**b1)*(CA**c1);
h.AGB = 1/DBH2;

BGB = a2*(DBH2H**b2);
h.BGB = 1/DBH2;

TB = a1*(DBH2HWD**b1)*(CA**c1) + a2*(DBH2H**b2);
h.TB = 1/DBH2;

fit AGB BGB TB / sur outest = Alldata_est;


 and then run I have received a notification of error as the following:

ERROR: Procedure MODEL not found.


Please help let me know whether there is any wrong in the code; or does SAS University Edition support/provide that procedure?


Thank you very much in advance

Bao Huy

PROC MODEL is under SAS/ETS , UE don't has this PROC .

A few SAS/ETS procedures are in the SAS University Edition: TIMESERIES, UCM and some others.


More SAS procedures, including PROC MODEL, are in the SAS-hosted SAS OnDemand for Academics.  As a student/researcher, you can use that environment for free under similar terms & conditions.
