### Comparing multiple cumulative incidence functions in the presence of competing risks

I have a survival/duration dataset with competing risks. The start years for the durations vary and range from 2010 to 2019. Each individual may only start once, e.g. during 2010, and therefore cannot ...

### Cumulative Incidence function and competing risks

Let $R_1,...,R_K$ be competing risks and put $T=\min(R_1,...,R_K)$ and $\delta = i$ if $T=R_i$. The cumulative incidence function is then defined as $F_i(t):=P(T\le t,\delta = i)$. The cause-specific ...

### Can I draw 1-CIF (Cumulative Incidence Function) as a survival curve?
