1. ### Is multidimensional ROC Curve Analysis a thing?

Hi, I'm a student of statistics and right now, in my course, we're studying validation of diagnostic tests. While learning about ROC Curves and AUC, I was wondering if does considering ROC Curves in the multivariate context make sense, and if so, how's the analysis performed and which are the...
