For a single ROC curve (with relevant AUC score), how can you calculate the confidence interval? (The data used to generate this ROC/AUC is available)
Given my relatively limited background in this area, this would be a case of 'the easier, the better'.
PS: please also inform me of any conditions that have to be fulfilled (if required by the formula you would use to calculate the CI).
Best Answer
are you looking for code? Many of the packages that make ROC curves also compute the CI. If you are using R look at the pROC package.
