Problem Note 61546: Cutoff node True Positives, True Negatives, False Positives, and False Negatives, might be incorrect
 |  |  |  |
By default, SAS® Enterprise Miner™ sorts binary target-variables in descending order to identify the target level of interest.
If you change the sort order to ascending, then count columns that are displayed by the Cutoff node are incorrect. The Results browser columns that are impacted are True Positives, True Negatives, False Positives, and False Negatives. The Cutoff node results assume a descending sort order, which leads to the mis-specification.
There are no errors or warnings to indicate a problem.
There is no workaround.
To obtain the correct values, add a Model Comparison node after the Cutoff node. The values that are displayed by the Model Comparison node are correct.

If a Cutoff node follows a node that models a binary target-variable, then the count columns in the Cutoff node might be incorrect. The columns are True Positives, False Positives, True Negatives, and False Negatives. The problem occurs when the target is sorted in ascending order.
