The ACF can be computed and graphed using the GAUSS function plotACF. The plotACF function takes the same inputs as the acf function: // Maximum number of autocorrelations k = 10; // Order of differencing d = 0;
WebThe ACF and PACF plots are produced. Hover the mouse cursor on the Lag 1 ACF bar to view the correlation value = .57, Lag 2 = 0.5, and Lag 3 = .4. The values are approximately the same as those obtained manually (with some minor differences in … WebInterpretation. Use the autocorrelation function and the partial autocorrelation functions together to identify ARIMA models. Examine the spikes at each lag to determine whether they are significant. A significant spike will extend beyond the significance limits, which indicates that the correlation for that lag doesn't equal zero.
