WebMay 30, 2013 · Combining proportions dying as you do is not giving you cumulative hazard. 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.
