Subject: Extrapolating Cox predicted risk
Dear all
I generated predicted risk of death for each subject in the study by
means of Cox proportional hazards model at 8 year of follow-up, a time
point at which follow-up was more than 90% complete. It is possible to
extrapolate to 10-year the predicted risk of each subjet by assuming
an exponential distribution?
Any help would be greatly appreciated.
Thanks for your consideration.
