pmut.gini: Calculate Model Prediction Gini with Standardization

In chengjunhou/pmut: Predictive Modeling Utility-function Toolkit

Description

This function calculates the standardized gini coefficient for model prediction.

Usage

pmut.gini(aa, pp, print = FALSE)

Arguments

aa	Vector of actuals, could be any value
pp	Vector of predictions, could be any value
print	Logical (defualt is FALSE), TRUE indicates printing the original gini before standardization

Value

A single numeric value for standardized gini

Examples

actuals = c(1,1,1,1,0,1,1,0,1,0,1,0,1,0,0,1,0,0,0,0)
predicts = rev(seq_along(actuals)); predicts[9:10] = mean(predicts[9:10])
pmut.gini(actuals, predicts, print=TRUE)
