Rates and Poisson regression
Epidemiological studies often involve the calculation of rates, typically rates of death or incidence rates of a chronic or acute disease. This is based upon counts of events occurring within a certain amount of time. The Poisson regression method is often employed for the statistical analysis of such data. However, data that are not actually counts of events but rather measurements of time until an event (or nonevent) can be analyzed by a technique which is formally equivalent.
