WebJun 2, 2024 · From figue 3.1, we notice that ARIMA(0,0,0) - ARIMA(2,0,0) are not a good chioce since ACF and PACF are significant different from zero for many lags and residuals have large variance. Meanwhile, the difference from ARIMA(2,0,1) to ARIMA(3,0,2) is not very large, because those models have identical ACF, PACF and residual plots.
