%description
Provides functions to estimate the proportion of treatment effect on a
censored primary outcome that is explained by the treatment effect on a
censored surrogate outcome/event. All methods are described in detail in
Parast, Tian, Cai (2020) "Assessing the Value of a Censored Surrogate
Outcome" <doi:10.1007/s10985-019-09473-1>. The main functions are (1)
R.q.event() which calculates the proportion of the treatment effect (the
difference in restricted mean survival time at time t) explained by
surrogate outcome information observed up to a selected landmark time, (2)
R.t.estimate() which calculates the proportion of the treatment effect
explained by primary outcome information only observed up to a selected
landmark time, and (3) IV.event() which calculates the incremental value
of the surrogate outcome information.
