The cumulative incidence function, denoted by F k,t/, is the probability of failure due to cause kprior to time t, It is defined as F k,t/DP,T t; Dk/; kD1;:::;K The cumulative incidence function is also referred to as the subdistribution function, because it is not a true probability distribution,
plots the cumulative incidence function CIF estimates If you specify a STRATA statement without the GROUP= option PROC LIFETEST overlays the cumulative incidence curves of the strata in the same plot If you specify a STRATA statement with the GROUP= option PROC LIFETEST produces a panel plot with one cell per stratum, and each cell contains the cumulative incidence curves for the groups within the given stratum,

needed to validate the plot A cumulative incidence plot is usually used to visualize the estimated probability of an event prior to a specified time For example Figure 1 is a cumulative incidence plot, In this plot, the y-axis is the cumulative incidence rate and x-axis is the duration of …
A cumulative incidence ratio plot is a good supplement in this case, Cumulative incidence is a measure of the probability or risk of event e,g, disease recurrence, It indicates what proportion of the population will experience the event during the specified time period, The cumulative incidence ratio
