I am trying to get an AUC curve for the model and I used the code:
proc phreg data = stanlong plots=AUC rocoptions(method=ipcw iauc); model (start,stop)*dead2(0) = plant surg ageaccpt / ties = efron; run; But I got an error message from the system:
Neither concordance nor ROC analysis is performed with the START/STOP specification of time.
Is there a way to obtain the AUC when I run proc phreg with time-dependent covariates?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
