Description: Provides influence function-based methods to evaluate a
        longitudinal surrogate marker in a censored time-to-event
        outcome setting, with plug-in and targeted maximum likelihood
        estimation options. Details are described in: Agniel D and
        Parast L (2025). "Robust Evaluation of Longitudinal Surrogate
        Markers with Censored Data." Journal of the Royal Statistical
        Society: Series B <doi:10.1093/jrsssb/qkae119>. A tutorial for
        this package can be found at
