Calculating AUC in Cox-regression prediction model with time-varying predictors

[Seirin Goldade]

I have used a cox survival analysis to construct a prediction model, and am trying to come up with some comparison of my model to existing prediction models. All I can find reported for existing prediction models are c-statistics. Is there a program to calculate a time-dependent c-statistic in stata? (I believe that, since my predictors are time-dependent - I have set up my dataset with multiple entries per patient coding the time-varying predictors, I cannot use the estat concordance command as a time-independent c-statistic is not possible.)

Hi, Seirin. I am currently facing a similar problem using estat concordance. I am wondering if you have resolved this issue and could share your solutions here. Thank you!
