Public Attributes
double	oobError

Detailed Description

Visitor that calculates the oob error of each individual randomized decision tree.

After training a tree, all those samples that are OOB for this particular tree are put down the tree and the error estimated. the per tree oob error is the average of the individual error estimates. (oobError = average error of one randomized tree) Note: This is Not the OOB - Error estimate suggested by Breiman (See OOB_Error visitor)
