Hi everyone,
I am doing mortality predictive index score with survival analysis (Cox
proportional hazard model) where I have one developmental dataset and one
validation datasset. To assess the discrimination ability of survival
analysis model. I guess I have to do C-statistic and compare the ROC curve.
I have tried to study the manual and stats website and that I ma not sure I
get an answer.
Please kindly advise,
Thank you for all your great help in advance
