In a previous post I mentioned that Poisson models can be used to carry out survival analysis tasks e.g. estimation of survival curves or even relative risk modelling. Yet, I never showed how this can be done. So I will close the gap today and highlight how this works from a purely mathematical vantage point.

### Who needs the Cox model anyway ?

October 4, 2012As provocative this title may read, it is hardly my creation and due credit should be given to Bendix Carstensen for giving numerous talks under this title and providing his teaching material and R source code for people to explore this point.

The title does neither imply that the Cox model is of no use at all, nor that one should abandon it even if only for the reason that the vast majority of biomedical literature makes use of it in one form of the other. Rather, it is meant to imply that one can put other more versatile regression models to the same uses and get out more out of the same data.
