The ISmDecisionTree interface is used to substitute missing data in series values using a decision tree.
ISmDecisionTree
The method uses categorical data. In ERROR: Variable (PP8) is undefined. categorical data must be presented as an integer array, in which numbers correspond to appropriate categories.
If ISmDecisionTree.Explained[i] = -1, this means that the i-th observation is missing: that is, it has not been clustered and should be classified as a member of one of the known classes using a decision tree.
Each of the series in the collection ISmDecisionTree.Explained must be defined with an array of non-negative integers that represent categories.
