Confidence Bands for Cumulative Incidence Curves Under the Additive Risk Model
1999
Shen, Yu | Cheng, S. C.
In the context of competing risks, the cumulative incidence function is often used to summarize the causeâspecific failureâtime data. As an alternative to the proportional hazards model, the additive risk model is used to investigate covariate effects by specifying that the subjectâspecific hazard function is the sum of a baseline hazard function and a regression function of covariates. Based on such a formulation, we present an approach to constructing simultaneous confidence intervals for the causeâspecific cumulative incidence function of patients with given risk factors. A melanoma data set is used for the purpose of illustration.
