Classification Tree Columns: ProbPrediction. [All unique values in Response Variable], Class Prediction Returns a ProbPrediction.{level} column for each value in the Response column. These columns contain the predicted score for each value in the Response column. The column with the highest score is returned in the ClassPrediction column.
