WOE and IV

PetePatel — Mon, 15 Oct 2018 10:41:51 GMT

Hi,

I have a large dataset (c.350k records( with unique identifier (ID), target and c. 1000 variables for which I need to calculate an information value.

Ideally, I would like to get a list of the variables with WOE and information value attached so I can start filtering.

Does anybody have any code that will allow me to do this efficiently in SAS?

Thanks

I recall attending a presentation on this topic at SAS Global Forum and SESUG:

I could suggest using PROC HPGENSELECT or PROC PLS to select the most 30 significant variables,

and get these 30 vaiables's WOE and IV.

If you want get better WOE and maximize IV to let your Score Card better and stronger ,

I wrote a paper about it , but you need SAS/IML and would cost you many time.

If you have SAS/EM's Score Card node ,that is your first choice.
