Holdout Forecast
With this feature you can conduct holdout forecasts using the new Model End Date
field, which has been added to the Schedule Model and Forecasts
function. A holdout forecast allows you to compare the forecast generated by Unified Demand Forecast (UDF) against actual sales data. You withhold some of this data from being considered in the modeling and forecasting processes for that period, and then you compare the results to the actual sales data that was withheld.
Holdout tests are best suited for measuring forecast accuracy in a proof-of-concept, pilot, or periodic analysis. Note that the holdout forecast is available only in the diagnostic mode.
