Aug.R.s.surv.estimate   Calculates the augmented estimator of the
                        proportion of treatment effect explained by the
                        surrogate marker information measured at a
                        specified time and primary outcome information
                        up to that specified time
R.s.estimate            Calculates the proportion of treatment effect
                        explained
R.s.surv.estimate       Calculates the proportion of treatment effect
                        explained by the surrogate marker information
                        measured at a specified time and primary
                        outcome information up to that specified time
R.t.surv.estimate       Calculates the proportion of treatment effect
                        explained by the primary outcome information up
                        to a specified time
d_example               Hypothetical data
d_example_surv          Hypothetical survival data
delta.estimate          Calculates treatment effect
delta.s.estimate        Calculates model-based or robust residual
                        treatment effect
delta.s.surv.estimate   Calculates robust residual treatment effect
                        accounting for surrogate marker information
                        measured at a specified time and primary
                        outcome information up to that specified time
delta.surv.estimate     Calculates treatment effect in a survival
                        setting
delta.t.surv.estimate   Calculates robust residual treatment effect
                        accounting only for primary outcome information
                        up to a specified time
fieller.ci              Constructs Fieller's confidence interval.
