AUC for logistic regression [was: (no subject)]

From: Spencer Graves

      What's AUC?  If you mean AIC (Akaike Information 
Criterion), and 
if you fit logistic regression using "glm", the help file 
says that glm 
returns an object of class "glm", which is a list containing 
among other 
things an attribute aic.  For example, suppose you fit a 
model as follows: 

      fit <- glm(y~x, famil=binomial()...)

      Then fit$aic returns the AIC. 

      You may also wish to consider anova and anova.glm. 

      hope this helps.  spencer graves

Dear R-helper,

I would like to compare the AUC of two logistic regression 

models (same 

population). Is it possible with R ?

Thank you
