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. WebDefinition of risk ratio. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. It does so by dividing the risk (incidence proportion, attack rate) in group 1 by the risk (incidence proportion, attack rate) in group 2.
