So say I have downsampled my data to account for lower bads. Now say I want to calculate KS statistic, does it make sense to calculate KS on the downsampled data only? Or should be scale it up? in case we decide to go with latter, how do we do it as npar1way doesnt have any weight option.

Can u tell me why do we always take minimum probability of that particular decile? Let's say the maximum segregation point lies somewhere in 3rd decile (assume the continuous case). If we take the minimum of 2 nd decile as score cut off we would have lost some events, instead of letting some non events in the model. Can u explain it to me in any other way?Arunansuhttps://www.blogger.com/profile/00078244849565826740noreply@blogger.comtag:blogger.com,1999:blog-7958828565254404797.post-23260755172667870262016-09-15T10:49:29.441-07:002016-09-15T10:49:29.441-07:00It is 58 vs 60. 75 was based on a different datase...It is 58 vs 60. 75 was based on a different dataset. The first image was just to show how KS works. I forgot to update it when i added PROC NPAR1WAY in the article.
