If I am not wrong, for a good predictive classifier both specificity and sensitivity should be more. So I need to know the cutoff where it is happening. Then I can predict the targets using the cutoff.

I also need a graph (Dual Axis) where Cutoff is on X-axis and Specificity and Sensitivity on y axis so that I can visualize the best cutoff.
