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

[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
