Input data. The 1st column should be time-to-event, and the 2nd column is event indicator (1=event, 0=censor). The rest of the columns are covariates/predictors used in the model. No character variable or missing is allowed. |

`tau` |
Truncation time. The resulting C tells how well the given prediction model works in predicting events that occur in the time range from 0 to |

`Rep` |
