I'm just beginning to explore the capabilities of BlueSky Statistics. I read in a review that ROC curves are among the available graphics but I cannot find them in the menus. Is it possible to draw them in BlueSky and also to get AUC and Youden's index?
BlueSky does not yet overlay ROC curves, so you would have to do one model for each of your independent variables, then follow Val's answer. Overlaying ROC curves is on the roadmap for future versions.
