LIFT CHART

Posted 02-27-2015 01:40 PM (1440 views)

Hi,

    I built a logistic regression model and then validated it on the validation data set. I get a good increase in lift for the first 6 deciles(increasing order from 60 to 10). But then , from 6th to 7th decile the lift drops steeply and again increases from the 7th decile to the 10th decile. What could be the reason for such a behaviour? How can I get a uniform increasing lift? Is there any solution to handle this problem?

Thanks,

Minal

what does the ROC plot look like?
how much did you tweak your logistic regression (selection, interactive or polynomial terms, etc)?
