ROC curve, probability , cut off

Hi,

 

How do I find the cut off value from the probaility on the ROC. I had to adjust to get a better AUC. Thanks

Which a analysis platform are you using?

 

Do you see an outline for the ROC details? If so, it contains the probabilities.

 

The AUC does not depend on the a cutoff.
