WebThe name survival analysis originates from clinical research, where predicting the time to death, i.e., survival, is often the main objective. Survival analysis is a type of regression problem (one wants to predict a continuous value), but with a twist. WebMay 30, 2013 · 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. It's like summing up probabilities, but since Δ t is very small, these probabilities are also small numbers (e.g. hazard rate of dying may be around 0.004 at ages around 30).
