Hello.
Please note proper mathematical notation coding:
J = t r u e _ p o s i t i v e s t r u e _ p o s i t i v e s + f a l s e _ n e g a t i v e s + t r u e _ n e g a t i v e s t r u e _ n e g a t i v e s + f a l s e _ p o s i t i v e s − 1 {\displaystyle J={true\_positives \over true\_positives+false\_negatives}+{true\_negatives \over true\_negatives+false\_positives}-1}
