Survival calibration objects
scalib(pred_risk, pred_horizon, event_status, event_time)(numeric vector, list, data frame, or matrix)
predicted risk values for the event at or before pred_horizon
(numeric value) the time of risk prediction.
(numeric vector) observed event status. The values of this vector should be 0 (event censored) and 1 (event observed).
(numeric vector) observed event times
an object of class 'scalib'
