    Enum Constants
    Enum Constant
    Description
    aggregateNodes
    If a Node's predicate value evaluates to UNKNOWN while traversing the tree, we consider evaluation of the Node's predicate being TRUE and follow this Node.
    defaultChild
    If a Node's predicate value evaluates to UNKNOWN while traversing the tree, evaluate the attribute defaultChild which gives the child to continue traversing with.
    lastPrediction
    If a Node's predicate evaluates to UNKNOWN while traversing the tree, evaluation is stopped and the current winner is returned as the final prediction
    none
    Comparisons with missing values other than checks for missing values always evaluate to FALSE.
    nullPrediction
    If a Node's predicate value evaluates to UNKNOWN while traversing the tree, abort the scoring process and give no prediction.
    weightedConfidence
    If a Node's predicate value evaluates to UNKNOWN while traversing the tree, the confidences for each class is calculated from scoring it and each of its sibling Nodes in turn (excluding any siblings whose predicates evaluate to FALSE).

    • values

      public static PMMLTreeModel.MissingValueStrategy[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static PMMLTreeModel.MissingValueStrategy valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
