These lecture notes are a companion for a course based on the book Modelling Survival Data in Medical Research by David Collett. Introduction: Survival Analysis and Frailty Models • The cumulative hazard function Λ(t)= t 0 λ(x)dx is a useful quantity in sur-vival analysis because of its relation with the hazard and survival functions: S(t)=exp(−Λ(t)).
