Oct 6, 2015 at 9:30 | comment | added | Scortchi♦ | No - use the logit function, whose inverse is in your code above. The logit of 0.5 is 0. | |
Oct 6, 2015 at 9:25 | comment | added | vonjd | @Scortchi: So basically if one wants to have a probability of $.5$ the threshold is $exp(.5)/(1-exp(.5)) = -2.54$ ? | |
Oct 6, 2015 at 8:59 | comment | added | Scortchi♦ | (1) Express the threshold in log odds rather than probability. (2) You need to describe how that scorecard's arrived at. I suspect it's by fitting a different model to yours, in which the predictors are binned & coefficients estimated for each bin. | |
