To do so, we derive a problem-independent upper bound on the proposed distance metric for given maximum allowable tree depth D: Proposition 2. This value defaults to 20 . min_rows: Specify the minimum number of observations for a leaf. This value defaults to 10 . Maximal Depth is used during the tree-growth phase. The range of possible values is between -1 and any integer greater than 0. A value of -1 represents "no ... Including number of levels (maximal depth) and number of nodes in a tree. ...
