IV.event                Calculates the incremental value of the
                        surrogate outcome information
R.q.event               Calculates the proportion of the treatment
                        effect (the difference in restriced mean
                        survival time at time t) explained by surrogate
                        outcome information observed up to the landmark
                        time
R.t.estimate            Calculates the proportion of the treatment
                        effect (the difference in restricted mean
                        survival time at time t) explained by primary
                        outcome information observed up to the landmark
                        time

delta.estimate          Estimates the treatment effect at time t,
                        defined as the difference in the restricted
                        mean survival time
delta.q.event.RMST      Calculates the residual treatment effect (the
                        difference in restricted mean survival time at
                        time t) after accounting for the treatment
                        effect on the surrogate outcome information up
                        to the landmark time
delta.q.event.semi.RMST
                        Calculates the residual treatment effect (the
                        difference in restricted mean survival time at
                        time t) after accounting for the treatment
                        effect on the surrogate outcome information up
                        to the landmark time
delta.t.RMST            Calculates the residual treatment effect (the
                        difference in restricted mean survival time at
                        time t) after accounting for the treatment
                        effect on the primary outcome up to the
                        landmark time
