Hello, in the Random Forest package the right daughter's index is saved and used for classification. When a tree is build, the right daughter's index is the left daughter's index + 1. My question is, if there is a reason for saving the index instead of calculating it. -- View this message in context: http://r.789695.n4.nabble.com/Saving-right-daughter-s-index-in-Random-Forest-required-tp4669541.html Sent from the R devel mailing list archive at Nabble.com.
