Problem Note 3391: Assessment charts may be incorrect if the flow involves partitioning,
priors, and the Ensemble node
If prior probabilities have been defined and a Data Partition node is
used, then the assessment charts created by the Assessment node may be
incorrect for the test and validation data sets.
There is no message indicating a problem, but you can usually see when
comparing models that the lifts of the various models may not converge
to the right place. The baseline model may also not be in the right
place.
This problem does not affect the scoring code or the scores which are
produced.
There is no circumvention for this problem.
