I am using following syntax to create compare ROC curves using SAS: Code for multiple and Single ROC : ---------------------------------------------------------------------------------------------------------------------- FILENAME REFFILE  '/folders/myfolders/sasuser.v94/ExcelData/ACPC/finalMCI_AD_ninsstat.xlsx'; PROC IMPORT DATAFILE=REFFILE DBMS=XLSX OUT=WORK.IMPORT; GETNAMES=YES; RUN; PROC CONTENTS DATA=WORK.IMPORT; RUN; ODS GRAPHICS ON; PROC LOGISTIC DATA=WORK.IMPORT PLOTS(ONLY)=ROC(ID=OBS); MODEL GROUP(EVENT='0')=ACC_GSH_Conc PCC_GSH_Conc CINGULATE_GSH_Conc; ROC 'ACC' ACC_GSH_Conc; ROC 'PCC' PCC_GSH_Conc; ROC 'CINGULATE' CINGULATE_GSH_Conc; RUN; PROC LOGISTIC DATA=WORK.IMPORT PLOTS(ONLY)=ROC(ID=OBS); MODEL GROUP(EVENT='0')=ACC_GSH_Conc; RUN; ODS GRAPHICS OFF;   Why SAS is giving two different values for single ROC curve? When I am plotting single ROC for 'alb' AUC value is different than I got by the syntax given above for single ROC (roc 'Albumin' alb;) with multiple ROC. ... View more
