calculate p value for ROC AUC by subgroups

JJ27 — Fri, 15 Dec 2023 18:45:03 GMT

I'm trying to see if there is a statistically significant difference in ROC AUC by subgroups in SAS. I can't use roccontrast because I only have one model. Here is my codes:

 proc logistic data=data plots(only)=roc;
         by Race;
         model htn (event='1') = bmi ;
         ods output roccurve=ROCdata;
         run;

Race has 4 categories: hispanic, black, white and other

I tried roccontrast, didn't work. I would really appreciate any guidance on this!
