# area under the curve

1. ### ROC curve from an array of Confusion Matrices (true positive rate and false positive rate)

How can us create an ROC curve from confusion matrices?
2. ### Area under the curve after 10-fold cross validation

Hi everyone, After performing a 10-fold cross validation, I now have area under the curve (AUC) for each of the 10 test subsets. I calculated the average AUC (0.63). I was interested to get the 95% CI, so I calculated the SE of the mean = 0.63 / sqrt root of 10 = 0.19. The 95% CI for...
