Plots of example data: Exponential and Weibull Cumulative Hazard Plots. The cumulative hazard for the exponential distribution is just \(H(t) = \alpha t\), which is linear in \(t\) with an intercept of zero. So a simple linear graph of \(y\) = column (6) versus \(x\) = column (1) …

Hazard rate in continuous time is a conditional probability that during a very short interval an event will happen: h ( t) = lim Δ t → 0 P ( t < T ≤ t + Δ t T > t) Δ t. Cumulative hazard is integrating (instantaneous) hazard rate over ages/time.
