I will be doing some testing tonight and endeavor to get this to the jamovi crew tomorrow. They are usually quite quick about pushing out the update

Currently hitting some problems making sure this update will roll out properly. Apologies, but it's coming!

Hey folks, the update has been pushed to jamovi. The DIF table error is gone, a crude DeLong test for differences between AUC's has been added, and the ability to combine ROC plots into a single image has been added. Please try it out and let me know your thoughts!

I just need to find it where it is :)

Can you give me a hint? :)

Hm. I've just learned that I'm not sure what the best route for updating on the user end is. If you go Modules > Manage Installed > Installed and remove PPDA and then re-install the module it will be updated. The new version is 1.0.2

The new version 1.0.2 is in the jamovi library. If you don't have it installed there will be an install button, if you have a previous version then there should be an update button. Is this not the case?

How do I get Optimal cut-off value for a continuous variable with a binary gold standard using ROC analysis?
Which module gives this option?
