ScoreDataProfet {Rprofet}

Score a Validation Data Set

Description

Function that scores the validation set using the scorecard from the ScorecardProfet object created by the training set.

Usage

ScoreDataProfet(data, card, id, target)

Arguments

data

The validation data set, which should be binned in the same way as the scorecard in the card argument.

card

A ScorecardProfet object. The object should be created by using the training set split from the same dataframe as the validation set.

id

ID variable.

target

A binary target variable.

Value

A dataframe of scored validation set.

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) ## WOE transformation of bins

md <- glm(default ~ student_WOE+balance_WOE+income_WOE, data=WOE_dat$WOE, family="binomial")
summary(md)

Score_card <- ScorecardProfet(object=WOE_dat, id="ID", target="default", GLModel=md,
                                 PDO = 50, BaseOdds = 10, BasePts = 1000, reverse = FALSE)
Score_card ## scorecard

## Scoring the data
# variable names needs to be the same as the Attributes on scorecard
colnames(binned)
colnames(binned)[3:5] <- c("student", "balance", "income") #change the variable name
Score_dat = ScoreDataProfet(data=binned, card=Score_card, id="ID", target="default") #scoring data
head(Score_dat)
