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!
See this note. When you are looking for a particular statistic in SAS, check the list of Frequently Asked-for Statistics (FASTats) in the Important Links section of the Statistical Procedures Community page.
