Hi there,
I am trying to do some linear regression in SAS enterprise miner. When I add polynomial terms in my model, it seems miner only allow me to do up to 3 degree polynomial? Would anyone suggest how can I do more than 3 degree in SAS, thanks in advance!
Best,
Peiyu
Hi Peiyu,
There is no limit on the number of polynomials in SAS/STAT linear modeling procedures including PROC REG.
For easy coding of polynomials, take a look at the EFFECT statement:

Funda,
Thanks for your suggestion. I will check it out. By the way, you said "There is no limit on the number of polynomials in SAS/STAT linear modeling procedures including PROC REG.", do you mean there is no limit in SAS enterprise miner as well? Please see attached pic below, whenever I tried to specify polynomial degree to 4 or 5, it will be forced set as 3. Any comment? Thanks.
It seems there is a limit on the "Polynomial Degree" property in EM. If you want to include only some polynomial terms, try to use the Term Editor.
Batho,
I just want to test to see how my model looks like if higher polynomial degree was included. At the mean time, I still want to keep those non-polynomial terms. Thanks.
