Assume, that x is input parameter, y is real output value and z is predicted output value. Early (20 years ago!) for sensitivity I have mean indicator of correction of prediction function changing depending of input parameter changing. So, Sensitivity is

{z(x[2] – z(x[1])}/{y(x[2] – y(x[1])}. In differ of accuracy, that one-point estimation, sensitivity is two-point estimation. But last years for sensitivity, at least on data mining field, mean some else.

Sensitivity = Recall = TPR = #TP/(#TP + #FN). What term can I use now instead of sensitivity for two-point estimation? Thanks beforehand for your answer. Regards, Sergey.
