rp.deviance: Compute deviance within nodes of classification trees
In treeClust: Cluster Distances Through Trees
rp.deviance R Documentation
Compute deviance within nodes of classification trees
Description
An rpart regression tree carries the deviance around (in the frame$dev
element). This function computes the deviance for classification trees.
Usage
rp.deviance(x, ...)
Arguments
x
An object of class rpart
...
Other arguments, currently unused.
Details
For a vector of leaf counts n whose sum is N, the deviance is (-2) times
the sum of n log (n/N), taking 0 log 0 as 0.
Value
Vector of deviances for every row in the tree's frame.
