gini: GINI Coefficient

Description

Calculates the GINI coefficient for a binary classifcation model

Usage

gini(...)
# S3 method for default
gini(actual, predicted, ...)
# S3 method for glm
gini(modelObject, ...)
# S3 method for randomForest
gini(modelObject, ...)
# S3 method for glmerMod
gini(modelObject, ...)
# S3 method for gbm
gini(modelObject, ...)
# S3 method for rpart
gini(modelObject, ...)

Arguments

…

additional parameters to be passed the the s3 methods

actual

A vector of the labels. Can be numeric, character, or factor

predicted

A vector of predicted values

modelObject

the model object. Currently supported glm, randomForest, glmerMod, gbm

Examples

# NOT RUN {
data(testDF)
glmModel <- glm(y ~ ., data = testDF, family="binomial")
Preds <- predict(glmModel, type = 'response')

gini(testDF$y, Preds)
# using s3 method for glm
gini(glmModel)

# }
