TDMR (version 2.2)

tdmModVote2Target: Analyze how the vote fraction corresponds to reliability of prediction.

Description

This function analyzes whether in different vote bins the trained RF makes predictions with different reliability. Only for RF-prediction in case of binary (0/1) classification. Expected result: The larger the fraction of trees voting for class 0 is, the smaller is the percentage of true class-1- cases in this vote bin. This function is somewhat specialized for the DMC2010-task.

Usage

tdmModVote2Target(vote0, pred, target)

Arguments

vote0

vector: which fraction of trees votes for class 0?

pred

vector: the predicted class for each record (0/1)

target

vector: the true class for each vector (0/1)

Value

a data frame with columns

vcut

vote cut v

count

number of cases with vote fraction in [v[i-1],v[i]]

pred0

fraction of 0-predictions

pCorr

fraction of correct predictions

pR

fraction of true 1-cases
