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?</P><P></P><P>Thanks,</P><P>Minal</P></BODY></HTML> Fri, 27 Feb 2015 18:40:15 GMT https://communities.sas.com/t5/SAS-Data-Science/LIFT-CHART/m-p/186408#M2276 MinalMMurkhande 2015-02-27T18:40:15Z Re: LIFT CHART https://communities.sas.com/t5/SAS-Data-Science/LIFT-CHART/m-p/186409#M2277 <HTML><HEAD></HEAD><BODY><P>what does the ROC plot look like?<BR />how much did you tweak your logistic regression (selection, interactive or polynomial terms, etc)?</P></BODY></HTML> Fri, 27 Feb 2015 18:44:02 GMT https://communities.sas.com/t5/SAS-Data-Science/LIFT-CHART/m-p/186409#M2277 M_Maldonado 2015-02-27T18:44:02Z
