“Competing risks” refers to the study of mortality patterns in a population of individuals, all subject to the same k ≥ 2 causes of death. The object is to isolate the effects of a given risk or subset of risks. Certain quantities, such as the “crude probability” of dying of a particular disease in the presence of the other competing risks, and cause-specific hazard rates, and functions of them, are estimable from observable data without unverifiable assumptions. Other quantities, such as the “net probability” of dying of a disease in the absence of other causes of death cannot be estimated without unverifiable assumptions on the joint distribution of times to death from the various causes of death. Bounds on the net probability are available, however. We review these concepts and related methods of estimation and inference.
