- How do I extract hazards from survfit in R? - Stack Overflow

It is a bit tricky since the hazard is an estimate of an instantaneous probability (and this is discrete data), but the basehaz function might be of some help, but it only returns the cumulative hazard. So you would have still have to perform an extra step.

- Aggregate Hazard Function in Price-Setting: A Bayesian ...

Until recently, the aggregate price reset hazard function remains a largely ignored topic in the macro literature. It begins, however, to draw more attention, because the competing theoretical models of sticky prices deliver clear mappings between speci–c aggregate hazard functions and implications for macro dynamics and monetary policy.

In turn, the hazard rate of the aggregate economy in period k can be expressed as h(k) = (k)h1(k)+[1 (k)]h2(k) where the weight (k) = S1(k) S(k) is a function of k and thus not constant along the hazard. Therefore, the aggregate hazard is a convex linear combination of individual hazards, although the weights vary with k.
