WebThe forecast accuracy is computed by averaging over the test sets. This procedure is sometimes known as “evaluation on a rolling forecasting origin” because the “origin” at which the forecast is based rolls forward in time. With time series forecasting, one-step forecasts may not be as relevant as multi-step forecasts. Web25 apr 2024 · ARIMA: MAPE of 2.1 percent ; The Simple Exponential Smoothing model did well to achieve a lower MAPE of 8.5 percent. The other two models outperformed it by producing an even lower MAPE. The ARIMA model emerged as the winner based on its lowest MAPE of 2.1 percent. 15.

Web13 lug 2015 · I would imagine ARIMA may be a plausible choice for your application. You would want to include seasonality. You need to be careful, however, not to overparameterize.

Since ARIMA has only lagged (rather than contemporaneous) values on the right hand side, fitted values of an ARIMA model coincide with 1-step-ahead in-sample forecasts. Thus in-sample MAPE can be obtained from the data vs. fitted values from ARIMA model. For out-of-sample MAPE, use rolling windows. prayug learning and teaching platformWeb11 lug 2016 · Applying different time series models (ARIMA, HOLT-WINTER) on the basis of MAPE.
