Do not believe everything you read on the internet!

the sd can be any positive real.

It may not be the problem, but with RStudio this error pops up when

Noah,
You might want to look at beta regression, using the betareg package on CRAN.
There is a JSS paper here that you might find helpful:

along with the vignettes for the package:

Since AFAIK they are related by a monotonous transformation, both
approaches should lead to the same ROC curve, shouldn't they? (not
tested)

Good point. I'm not sure how I missed that.
This does lead to an additional question:

Unfortunately there's a known bug which prevents you from setting the
