https://communities.sas.com/t5/Statistical-Procedures/PROC-AUTOREG/m-p/41435#M1773 I am trying to use proc autoreg and I get the following error"<BR /> <BR /> ERROR: Procedure AUTOREG not found.<BR /> <BR /> I replace "autoreg" with proc reg and it seems to be working. Is there a component that is missing from my SAS installation?

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).
