WebFor MA models, the PACF will dampen exponentially and the ACF plot will be used to identify the order (q) of the MA model. ARMA Models ARMA models (including both AR and MA terms) have ACFs and PACFs that both tail off to 0. These are the trickiest because the order will not be particularly obvious.
