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.
Example code
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;
I've tried:
- regression predefined = (aictest(td easter));
- regression aictest = td easter;
- aictest = td easter;
The documentation has syntax examples for regression predefined = and regression uservar = but it doesn't give details on aictest.
Any pointers would be appreciated.
Thanks,
Alice
