WebJul 29, 2024 · 1 Your title asks about ACF but you actually display PACFs. A lag-1 correlation induces a lag-2 correlation (and lag-3, 4 etc). Lag-1 and lag-2 correlations induce lag-3 and higher correlations, etc. So actual ACFs for AR models tend to show shrinking (and eventually, geometrically decreasing) correlations across lags. WebPACF. Here the signature is AR(2) because of 2 spikes in PACF. 10 MA signature: noisy pattern, sharp cutoff in ACF (usually negative at lag 1), gradual decay in PACF.
