below for reference) but thus far I can only find a version in Hmisc
package which requires survival data. Any idea what the best approach is
for cross-sectional data?
Thanks

I am trying to compare the performances of several methods using the AUC0.1
and

goes to
0.1 not 1)
I came to know about the Mcneil Hanley test from Bernardo Rangel Tura
and I referred to the original paper for the calculation of "r" which is an
argument of the function
cROC. I can only find the

Comparing differences in AUC from 2 different models
Hi,
I would like to compare differences in AUC from 2 different models, glm and gam for predicting presence / absence. I know that in theory the model with a higher AUC is better, but what I am interested in is if statistically the increase in AUC from the glm model to the gam model is significant. I also read quite extensive discussions on the list about ROC and AUC but I still didn't find
