WebMay 17, 2024 · We will use both of ARIMA and ETS models to predict and see their accuracy against the test set (2024, Jan-Dec). In the first step, we need to plot visualization between ARIMA Model, ETS Model, and our actual 2024 data. But since ggfortify package doesn’t fit nicely with the other packages, we should little modify our code to show … WebBased on the relation between ARIMA and ETS (see Section 8.4 ), we do not need to test some of the combinations of models when selecting ARIMA orders. For example, if we already consider ETS (A,N,N), we do not need to check the ARIMA (0,1,1) model. The recommendations for what to skip in different circumstances have been discussed in …
