    Predicted values from Neural Network may be incorrect for observations
    with missing input values if a standardization method is specified

    Product: Enterprise Miner
    Component: Neural Network node
    Priority: ALERT

      In the Neural Network node of Enterprise Miner, if a standardization
      method is specified for the target variable (STANDARD DEVIATION, RANGE
      or MID RANGE), predicted values will be incorrect for observations with
      missing input values.

      The target standardization method is specified through the NETWORK
      sub-tab of the ADVANCED tab of the Neural Network node when you right
      click on the TARGET node, select properties, click on the TARGET tab and
      then the STANDARDIZATION pull-down menu.
