Probabilities from LogisticRegression
I found a post which talks about "converting" confidence values into probabilies using the PlattScaling operator.
However, I am finding that the confidence values which are produced following PlattScaling are not the logistic regression probabilies that I would expect (i.e. taking the callibration parameters for the logistic regression generated by RM (which are spot-on) and manually computing the probability as prob = exp / [1 + exp] ).
what am i doing wrong? and is there a way to extract the logit probabilities?
