Cox model approximaions (was "comparing SAS and R survival....)
...t of my data set !
I was thinking about distributing the events uniformly in each interval.
What do you think about this option ? Can I expect a better
approximation
than directly applying Breslow or Efron method directly with the grouped
event data ? Finally, it becomes a model problem more than a
computationnal
or algorithmic one I guess.
