It is not OK. Post to a statistical list, like stats.stackexchange.com , instead. -- Bert

Dear friends - I hope it is OK to ask a question on the principles of survival analysis. I'm a medical person in this project, but wonders about the statistical methods proposed. We have a huge dataset and assumption of proportional hazard is said to be fulfilled if survival time is fractionated into short, intermediate and long time survival. I wonder if it should not be better to have a more generalized method encompassing the entirety of the observation period. Best wishes Troels Ring, MD Department of nephrology Aalborg, Denmark
