Re: BinaryClassificationMetrics - get raw tp/fp/tn/fn stats per threshold?

Given recall by threshold, you can compute true positive count per threshold by just multiplying through by the count of elements where label = 1. From that you can get false negatives by subtracting from that same count. Given precision by threshold, and true positives count by threshold, you

BinaryClassificationMetrics - get raw tp/fp/tn/fn stats per threshold?

Hi, BinaryClassificationMetrics expose recall and precision byThreshold. Is there a way to true negatives / false negatives etc per threshold? I have weighted my genuines and would like the adjusted precision / FPR. (Unless there is an option that I've missed, although I have been over the
