[R-sig-ME] ROC Curve GLMM

[Chris Mcowen]

Dear List,

I am wanting to test how good my model derived from my training data is at predicting my test data. To do this i have been advised to calculate the receiver operating characteristic (ROC) curve.

I cant find a function to do this with a glmm - is there one? 

And second, would you recommend this approach, or is there a better, alternative?

Thanks

Chris
