# Definition of Lift

Hi All,

Can anyone explain how RM is defining "lift" as it pertains to the binomial classifer performance operator?

I am used to lift, in this sense, as being the proportion of the top X% of cases sorted by confidence/probability descending, divided by the overall proportion of positive cases in the data. I cant find how you would set the X% in RM. Is my definition correct and is a X% set (non changeable)?

Thanks!
