Generating the AUC with proc logistic

[JasonL]

Hi there,

I'm trying to obtain the AUC with proc logistic.  I have something like this:

proc logistic data=MyData;

     model DepVar = Var1 Var2 Var3;

run;

or

proc logistic data=MyData;

     model DepVar = Var1 Var2 Var3  / selection=stepwise;

run;

What options do I need to add to get the AUC statistic?

Thank you!

Is it just the "c" statistic in the following table?

Association of Predicted Probabilities and Observed Responses      

Percent Concordant	68.3	Somers' D	0.374
Percent Discordant	30.9	Gamma	0.377
Percent Tied	0.8	Tau-a	0.100
Pairs	1919	c	0.687

Yes.  Mark yourself as correct.
