Description: In clinical trials, endpoints are sometimes evaluated with
        uncertainty. Adjudication is commonly adopted to ensure the
        study integrity. We propose to use multiple imputation (MI)
        introduced by Robin (1987) <doi:10.1002/9780470316696> to
        incorporate these uncertainties if reasonable event
        probabilities were provided. The method has been applied to Cox
        Proportional Hazard (PH) model, Kaplan-Meier (KM) estimation
        and Log-rank test in this package. Moreover, weighted
        estimations discussed in Cook (2004)
        <doi:10.1016/S0197-2456(00)00053-2> were also implemented with
        weights calculated from event probabilities. In conclusion,
        this package can handle time-to-event analysis if events
        presented with uncertainty by different methods.
