Problem Note 33780: INCORRECT STANDARD ERROR IN DEMANDS TABLE WHEN BACK= IS USED
 |  |  |  |  |
If the BACK= option is used in the PROC HPFENGINE procedure statement to fit a model to intermittent data, then all of the demand values in the forecast horizon region are included in the Demands table.
If there is more than one value in the horizon or forecast region then the Standard Error for the Estimate of Mean Demand per Period, labeled "Std", reflects values based on multi-step forecasts of non-intermittent data. However, these values should be constant for all demands in the horizon or forecast region.
At this time there is no circumvention available.
