Hello.

Please note proper mathematical notation coding:

$$J = {true\_positives \over true\_positives+false\_negatives}+{true\_negatives \over true\_negatives+false\_positives}-1$$
 * $$ {} $$
 * $$J = \frac{\text{true positives}}{\text{true positives}+\text{false negatives}}+\frac{\text{true negatives}}{\text{true negatives}+\text{false positives}}-1$$
 * $$J = \frac{\text{true positives}}{\text{true positives}+\text{false negatives}}+\frac{\text{true negatives}}{\text{true negatives}+\text{false positives}}-1$$
 * $$J = \frac{\text{true positives}}{\text{true positives}+\text{false negatives}}+\frac{\text{true negatives}}{\text{true negatives}+\text{false positives}}-1$$
