WebA hazard rate is the limit of the ratio of events in an interval to the group size divided by the length of time. The hazard rate formula finds the rate for time intervals approaching zero, producing the instantaneous hazard rate. It is the probability that an unaffected subject experiences the event between time t and t + Δt, where Δt ...
