Notable proposals for regression problems are the so-called regression error characteristic (REC) Curves and the Regression ROC (RROC) curves. In the latter, RROC curves become extremely similar to ROC curves for classification, with the… 14 Sep 2019 Given that even elementary issues like simple statistical testing have of multiple comparisons (MC) controversies to frequentist statistics, and Drug Inf J. 2001;35:1469–78. 2019;73(Suppl 1):106–14. http://www.tandfonline.com/doi/pdf/10.1080/00031305.2018.1529625. 57.
