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 American Express made the following annotations on Tue Jun 12 2012 05:44:05 ****************************************************************************** "This message and any attachments are solely for the intended recipient and may contain confidential or privileged information.
