Hi,
I have a logit model built in R which I am trying to validate . Could you
please help me with creating lift charts and area under ROC for the same. I am
trying to use package ROCR
The indicative code for this is :
newlogit3<- glm(Attrition_ind ~ Time.in.AXP+ Age
+as.factor(Increase.in.Rating.in.Current.year)
+as.factor(Below.Market.Merit.Budget)+as.factor(Drop.in.AIA)
,family=binomial(link="logit"),data=Attrition_data_2)
summary(newlogit3)
to predict I have a have used the code
Test_data_1011 <- read.csv(file="TEST DATA_10_11.csv", header =
TRUE, sep = ",", row.names = "employee_id", stringsAsFactors
= TRUE)
pred3 = predict(newlogit3,Test_data_1011 ,type = "response")
Warm regards,
Dwaipayan
