WebSee Page 1. Clearly, the least accurate method was the OLS, for both ETS and ARIMA forecasts and across all forecast horizons. OLS only improved forecast accuracy over the base forecasts at the top level. This was due to ignoring the differences in scale between the levels of the hierarchy and any relationships between the series. WebApr 26, 2024 · The ARIMA model is great, but to include seasonality and exogenous variables in the model can be extremely powerful. Since the ARIMA model assumes that the time series is stationary, we need to use a different model. SARIMA. SARIMA Formula — By Author. Enter SARIMA (Seasonal ARIMA). This model is very similar to the ARIMA …
