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
