WOEProfet {Rprofet}

WOE Transformation

Description

Function that calculates the WOE for each bin and the information value for each variable.

Usage

WOEProfet(data, id, target, varcol)

Arguments

data

Dataframe of binned variables.

id

ID variable.

target

A binary target variable.

varcol

Vector of variables to have WOE transformation.

Value

A list with the following components.

Bin

Dataframe with the binned variables and their WOE values.

WOE

Dataframe with the WOE values.

IV

Each attribute and their associated information values.

vars

A list containing the different WOE values for each attribute.

Examples

mydata <- ISLR::Default
mydata$ID = seq(1:nrow(mydata)) ## make the ID variable
mydata$default<-ifelse(mydata$default=="Yes",1,0) ## Creating numeric binary target variable
binned <- BinProfet(mydata, id= "ID", target= "default", num.bins = 5) ## Binning variables
WOE_dat <- WOEProfet(binned, "ID", "default", 3:5)
head(WOE_dat$Bin)
head(WOE_dat$WOE)
WOE_dat$IV
head(WOE_dat$vars$income)
