Leaf node

As explained in Statistics Slam Dunk

A terminal node is an endpoint of a decision tree at which a final prediction is assigned and no further split occurs.

How Statistics Slam Dunk covers it

How deep it goes

Defines leaves as tree endpoints and connects them to splits, but stops short of explaining their internal fitting mechanics.

Examples

Uses an NBA regression tree with 10 leaves predicting regular-season wins from screen assists, deflections, and other predictors.

What you can do after

Evaluate/understand final regression-tree predictions by reading leaf endpoints and the conditions that lead to them.

How it connects

Connects leaf nodes to regression trees, predictors, splits, and if-else rules.
