Hello everybody!

I've run a cox proportional hazards model for survival analysis in a cohort of pancreatic cancer patients with SPSS v. 25 and I want to

1. compare the accuracy (with the Harrell's C) of my model with classical staging

2. to measure the Cs of my model after bootstrapping

I've tried the macro available in the IBM web site, but it does not work (many errors)

...anyone can help?

THANKS
