AUC What should the arguments for the function roc be in order to calculate AUC? In the book, this is listed as yTEST, but I am not sure what
value this represents.
Answers and follow-up questions Answer or follow-up question 1
yTEST is the observed labels (0 and 1).
The first element in the roc function is the predictions (probabilities) and the second element is the labels (ground truth).
Please do ?roc for more information.
