Averaging 10 ROC curves

[martinmargh]

Hi! I have computed 10 ROC values to test my model's performance (I'm working with GLMMs) with a 10-fold cross-validation. Because I need an averaged value of AUC, I stored my results in a list and saved as an rds file to compute the mean between those curves.
I'm looking for a function or similar to compute the average ROC and AUC with a measure of error (e.g. confidence intervals as the ones provided by the roc or standard deviation estimates).

Thank you!

Hi, thanks for the report!
Would that be covered by issue #41?

Hi! Yes, I'm exactly looking for a function that takes as input my roc values. Is it available for pROC?
Thank you!

There's code in ci.thresholds that does something like that, but it's not exposed in any way.

Ok, it seems perfect to compute ci for the averaged roc curve...but I can't find a way to compute this averaged curve.
