WOEplotter: Visualizing WOE and Target Rates

Description

Function generating three plots: WOE value for each bin, target rate for each bin, and the frequency for each bin.

Usage

WOEplotter(data, target, var, color = "#0066CC")

Arguments

data

Dataframe containing binned values and a binary target variable.

target

A numeric binary target variable.

var

The desired WOE binned attribute to visualize.

color

A hexadecimal value representing a specific color.

A list of the hexadecimal colors can be found at this link http://www.sthda.com/sthda/RDoc/images/hextable.gif

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
WOEplotter(binned, target= "default", var= "income_Bins")
##--Changing Colors------------------------------
