WebThe auto.arima () function in R uses a variation of the Hyndman-Khandakar algorithm ( Hyndman & Khandakar, 2008), which combines unit root tests, minimisation of the AICc and MLE to obtain an ARIMA model. The arguments to auto.arima () provide for many variations on the algorithm. What is described here is the default behaviour. WebDec 15, 2024 · 1 Answer. Sorted by: 2. These plots look pretty decent to me. I would not expect better behavior even if the model happened to coincide with the true DGP. (You could simulate from the estimated model, fit the model on the simulated data and inspect its residuals to see for yourself.) Take a look at cross correlations for lag ≠ 0, too.
