Censoring Competing Risks
Time to cancer, but competing risk of death
•Suppose we censor deaths
–If deaths represent noninformative censoring
•People who died of, say, MI neither more nor less likely to get cancer in the near term
•Estimates desired hazard rate
–If deaths represent informative censoring
•Estimates cause specific hazard in presence of unchanged risk of competing event
•Results are not generalizable to a population with an altered risk of death
