Read acf and pacf plot
WebThe function acf computes (and by default plots) estimates of the autocovariance or autocorrelation function. Function pacf is the function used for the partial autocorrelations. Function ccf computes the cross-correlation or cross-covariance of two univariate series. Webhansfinans • 4 min. ago. I’ve been taught you should look at the cut off, such that the ACF cuts of at lag 6, and for the PACF after lag 1. Generally you shouldn’t make the model to complex with increasing the numbers of lags, and a rule of thumbed is to stay below a total of 10. Try different models such as ARMA (6,1), ARMA (5,1), ARMA ...
