SUPPORT / SAMPLES & SAS NOTES
Problem Note 34221: ERROR: Read Access Violation in Task [HPFENGINE] when log transformation is used
 |  |  |  |  |
PROC HPFENGINE returns the following warning and error messages:
- WARNING: Invalid transformation for the variable y.
- ERROR: Read Access Violation in Task [ HPFENGINE ].
if the following conditions are met:
- a holdout sample is used
- the data in the fit region are all positive
- a transformation requiring positive numbers is used
- a UCM or ARIMA model is fit, and
- the holdout region contains a 0 value.
Please note that some of the aforementioned conditions may be satisfied by the transformation and model automatically selected by the HPFENGINE procedure. The conditions do not have to be explicitly specified in the procedure syntax.
No circumvention is available for this problem other than to remove the zero value(s) of the FORECAST statement variable in the forecast region.
A hot fix is under consideration for this problem.
