I like to figure out how I can retrieve an incidence rate based on a hazard function. So background could be that my hazard function models the prob of the event based on the age of a person (t = time since birth). Of course, the current age distribution in my population is relevant.
So my understanding is as follows:
- Hazard function h(t): gives me the probability that the event occurs within the next interval based on the assumption that until t there was no event
Now I like to calculate an incidence rate - so percent of new events within one interval (e.g. one year) but independently of single cases.
What is the relation between the concept of hazard function or maybe cumulative hazard function and a general incidence rate?
