    SN-003391 OUTSTANDING PROBLEM

    Assessment charts may be incorrect if the flow involves partitioning,
    priors, and the Ensemble node

      Product: Enterprise Miner
    Component: Assessment node
     Priority: ALERT

      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.

      Hot fix 81DT02 is available to fix this problem. This fix applies
      to the client side.

      For more information on the hot fix, view information at the following
      location:
