Revisiting the cumulative incidence function with competing risks data

Abstract We consider estimation of the cumulative incidence function (CIF) in competing risks Cox model. study three methods. Methods 1 and 2 are existing methods while method 3 is a newly proposed method. Method constructed so that sum CIF’s across all event types at last observed time guaranteed, assuming no ties, to be equal 1. The performance examined via simulation, they illustrated on data from field computer code comprehension. exhibits comparable terms bias variance, better than confidence interval coverage rates.
