Hi,
Expost forecast is used to check whether the model selected for statistical forecasting is correct or not.
For Example:
If You take 3 years of historical data then the system will take one year of historical data in past (left most data in the planning book) to forecast for remaining 2 years in past. This forecasted value is called expost forecast and is compared with the actual sales in the past. If the forecast accuracy( in % terms) is as desired then the selected model is good enough to forecast for future.
Thanks
