IBM® Db2 for z/OS Decision Tree Model Nuggets

The Decision Tree model nugget displays the output from the modeling operation and also enables you to set some options for scoring the model.

When you run a stream that contains a Decision Tree model nugget, the node adds two new fields, the names of which are derived from the target.

Table 1. Model-scoring field for Decision Tree
Name of Added Field Meaning
$I-target_name Predicted value for current record.
$IP-target_name Confidence value (from 0.0 to 1.0) for the prediction.
Note: Due to limitations in Db2® for z/OS®, the column names might be truncated.
