Has anyone successfully used aictests with proc X12?
I've gone through the documentation and it's unclear to me what the syntax is. Documentation https://support.sas.com/documentation/onlinedoc/ets/132/x12.pdf go to the section on the regression spec.
proc x12 data = NSA date = period interval = qtr; var NSA; regression aictest = (td easter); arima model = ((0,1,1)(0,1,1)); forecast lead = 8 outfcst; x11; output out = result a1 d10 d11 d12 d13; run;
The documentation has syntax examples for regression predefined = and regression uservar = but it doesn't give details on aictest.
Any pointers would be appreciated.
