smbinning.factor.gen {smbinning}

Utility to generate a new characteristic from a factor variable

Description

It generates a data frame with a new predictive characteristic from a factor variable after applying smbinning.factor or smbinning.factor.custom.

Usage

smbinning.factor.gen(df, ivout, chrname = "NewChar")

Arguments

df

Dataset to be updated with the new characteristic.

ivout

An object generated after smbinning.factor or smbinning.factor.custom.

chrname

Name of the new characteristic.

Value

A data frame with the binned version of the original characteristic.

Examples

# Load library and its dataset
library(smbinning) # Load package and its data
pop=smbsimdf1 # Set population
train=subset(pop,rnd<=0.7) # Training sample

# Binning a factor variable on training data
result=smbinning.factor(train,x="home",y="fgood")

# Example: Append new binned characteristic to population
pop=smbinning.factor.gen(pop,result,"g1home")

# Split training
train=subset(pop,rnd<=0.7) # Training sample

# Check new field counts
table(train$g1home)
table(pop$g1home)
