Inserting Levels
All nodes on a single level represent a segment of the same decision variable. When you first create a decision tree, it does not contain any levels (predictors) or condition nodes.
Typically, you create your tree by inserting splits. However, you can also insert levels if you know the variables you want to use, in what order, and you want to capture this design before deciding the splits.
A level is automatically created when you insert a split. Alternatively, you can insert all of the levels in your decision tree before adding splits because the
Insert Level command is available only when you first begin building a decision tree. After you add a split, this command is not available. However, you can add additional levels by choosing an existing node and selecting
