Improving ROC curves - Youden index
Posted: Sat Mar 24, 2018 12:05 pm
First of all. Thanks for including ROC curves into jamovi... It is really handy and easy to use.
Here are some suggestions:
- display multiple curves on the same graph (i dabbled with pROC in R and made a script which I adjust as needed - if you would like me to I can upload it here)
-it would be nice to have the option to have curves in same colour but different shape (full, dotted, dashed, dot-dash-dot and so on)
-calculate the so called Youden index which will show the optimal cutoff value (best combination of specificity and sensitivity)
Thanks
