I am trying to compute a 95% confidence interval for the area under an ROC curve using the pROC package. The estimate for the area has a value of 0.9092, which looks fine. However, the estimate for the confidence interval is "0.95% CI: 0-0 (DeLong)", which I don't understand. I'm wondering what could cause this to happen.
