PROC AUTOREG

[model_coder]

I am trying to use proc autoreg and I get the following error"

ERROR: Procedure AUTOREG not found.

I replace "autoreg" with proc reg and it seems to be working. Is there a component that is missing from my SAS installation?

[model_coder]

I confirmed that we don't have SAS/ETS component and therefore I can't use proc autoreg. Is there anyway I can use proc mixed to implement autoregression where lag = 4? I only saw examples of proc mixed with type = AR(1).
