Pair (i, j) is comparable when i has a cause-1 event and either
T_i < T_j or j experienced a competing event (Fine-Gray risk set);
concordant when the predicted cause-1 risk of i exceeds that of j,
ties one half.
Usage
Sscompv(time, event_type, predicted_F)
Arguments
- time
Observed times.
- event_type
0 censored, 1 cause of interest, >= 2 competing.
- predicted_F
Predicted cause-1 cumulative incidence.
Value
List with estimate, concordant, tied,
comparable.
