Descriptif
There are many quantitative measures for which there is a zone of overlap between the measures made in both the cases and non-cases. Thus, we have to choose a threshold that allows us to decide on the best option. The ROC curve, which is explained again to viewers, is the method that answers this question. It also makes it possible to compare various methods. The construction of the ROC curve is explained and illustrated point by point.
