WebbBreiman, L. (2001) defined a random forest as a classifier that consists a collection of tree-structured classifiers {h(x, Ѳ k), k = 1,...} where the { Ѳ k} are independent identically distributed random vectors and each tree casts a unit vote for the most popular class at input x. For the kth tree, a random vector Ѳ k is generated, Webb28 nov. 2016 · Re: How to write code for classification tree in sas studio Posted 11-28-2016 11:51 PM (1355 views) In reply to Macy If you are using PROC HPSPLIT , check CODE statement.
