Editing Splits

Decision tree counts (see Counting and Recounting Decision Trees for more) are cleared when you modify one or more splits.

1. Identify an existing node that you want to edit and select its parent node.
   

   Note The parent node is the node that contains the values of the decision node you want to edit.

2. Select Edit > Edit split or select the command from the shortcut menu.
3. Complete the appropriate step for the type of decision node you are editing:

   Editing Splits for Numeric and String Decision Nodes

   Decision Node Variable Type	Step
   Numeric variable	Keep the Lower limit inclusive selection or select Upper limit inclusive. Add a branch, remove a branch (by clicking X on the right side of a row), group rows, or any combination of these steps. Caution Removing a branch also deletes its child nodes from the tree. Attempting to revert the deleted branch by re-entering the original value does not recreate the child nodes. You would need to manually recreate the original child nodes in the Tree view canvas.
   String variable	Group, ungroup, or reorder rows.

4. Click APPLY to save your changes.

If a node is currently selected in the Tree View, then these key bindings are available to select a nearby node. The view content scrolls if necessary so that the newly selected node is visible. This type of navigation can be useful when working with a large decision tree. These key bindings function only in the Tree View.
