Hazard Function

The hazard function is the probability that an individual will experience an event (for example, death) within a small time interval given that the individual has survived up to the beginning of the interval. It can therefore be interpreted as the risk of dying at time t.
h(t)= number of individuals experiencing an event in interval beginning at time(t) / (number of individuals surviving at time t)x(interval width)
