I have been trying to understand the results of a CRT decision tree, my question is if the terminal nodes should be mutually exclusive? I am asking this because by reading the terminal nodes some variables seems to overlap each other.
For instance some terminal nodes "share" the same profession:
Node 23: carpenter, plumber, sole trader, truck driver
Node 24: plumber, truck driver, teacher, retired.
Probably I am reading the results incorrectly because it should not happen, at least in theory.
