From expression (1), it is clear that restricting the analysis to individuals failing from the cause of interest l will affect both the set risk over time that is, n j at each time t j —and the complement to one of the survival function,, as much as the censoring and the competitive causes are large.
As I l (t) depends on both the hazard function for cause l, λ l (t), and the hazard functions for other competitive causes, there is no one-to-one correspondence between λ l (t) and I l (t), that is, the relationships between the explanatory variables and λ l (t) may not reflect the relationships between explanatory variables and I l (t) (Andersen et al, 2012).
In a non-parametric setting, I l (t) can be estimated as follows: where S(t j −1) is the survival function at time t j −1, d lj is the number of subjects failed from cause l at t j, n j is the number of subjects at risk at t j, that is, subjects still in follow-up and not failed from any causes at time t j, and l=1,…, k are the competitive causes.
