delta.estimate.RMST

numeric vector, observed event times for the primary outcome in the treatment group.

xone

numeric vector, observed event times for the primary outcome in the control group.

xzero

numeric vector, event/censoring indicators for the primary outcome in the treatment group.

deltaone

numeric vector, event/censoring indicators for the primary outcome in the control group.

deltazero

time of interest for treatment effect.

weight

TRUE or FALSE; if TRUE then only delta is returned, if FALSE then delta and restricted mean survival time for each treatment group is also returned

delta.only

Helper function; used by delta.estimate function

internal

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.
