WebForecast Accuracy Measurement and Improvement. Forecast accuracy measurement is important for a number of reasons including the investigation of existing or potential problems in the supply chain and ensuring that the forecasting system is under control. It is also an important component in safety stock calculation. 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.
