So I want to check if my equation has autocorrelation. So I type in AR(1) into the equation. But it also gives me a SIQMASQ variable out. Why does it do this? I remember in the past it didn't do this also the method is changed to a Method: ARMA Maximum Likelihood (OPG - BHHH)


Can't I just use my OLS Regression and add an AR term with it?

SIGMASQ is the estimated variance of the innovations to the error process.
