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
