Is there a way to display the cutoff value on the ROC curve with a dot and a number? Please provide a reference example.
Hi @s22d704,
You can use the Crosshair tool '"+" symbol) on any graph to display individual X-Y values :

More infos about the tools in JMP :The Tools Menu - JMP User Community
For binary classification models, you can also have a look at Decision Thresholds Report which may help you to assess the impact of the decision threshold value on specificity, sensitivity, precision, accuracy, F1-score, Matthews Correlation Coefficient, ... :

Hope this answer may help you,
