A simple way to limit a tree’s size is to directly regulate its depth, the size of its terminal nodes, or both. We can define the depth of a node as the number of parent nodes that have come before it. For instance, the initial node has depth 0, the children of the first split have depth 1, and the children of the second split have depth 2. direkte cash flow ermittlung
