Dear Statalist community,

I am using a nationwide dataset with survey sampling to determine a specific surgical outcome during readmissions. I have read the Survey Data and Survival Analysis Reference Manuals and I could not find how to obtain the ROC curve and the Harrell's C statistic after a svy: stcox model. Also, how do you typically assess the goodness-of-fit test using svy: stcox.

I would greatly appreciate if someone can help me with this.

Jesus
