- Parameters:
event (array-like, shape = (n_samples,)) – Contains binary event indicators.
time (array-like, shape = (n_samples,)) – Contains event/censoring times.
- Returns:
time (array, shape = (n_times,)) – Unique times.
cum_hazard (array, shape = (n_times,)) – Cumulative hazard at each unique time point.
