How to create lift chart and ROC curve in R
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....

Validation of logistic models in R 2.12
...2.12 and I cannot install ROCR.
I have gone to a point where I have the predicted values using the code:
pred1 = predict(trainlogit1,testdata_1, type = "response")
How do I proceed from here? Is there another way in which I can plot lift charts?
My model output is:
Call:
glm(formula = Attrition_ind ~ Time.in.com + UV_LTIA_Base + as.factor(new_hire_ind) +
as.factor(promotion_ind) + as.factor(Time.in.comp...5.years) +
as.factor(Change.in.Job.Code) + Positioning_num + as.factor(Below.Guideline) +
as.factor(Above.Guideline) + as.factor(Drop.in.Rating.in.2010) +
as.factor(Increase....
