Calculate the unadjusted restricted mean survival time (RMST) — rmst_unadjust • bunsen

Estimate the unadjusted RMST (point estimate).

rmst_unadjust(time, status, trt, tau)

Arguments

time: A vector containing the event time of the sample.
status: A vector containing the survival status of the sample.
trt: A vector indicating the treatment assignment. 1 for treatment group. 0 for placebo group.
tau: Numeric. A value for the restricted time or the pre-specified cutoff time point.

Value

A data frame including the survival time for each trt and the difference. SE were also calculated.

mu0: Mean survival time for trt0
se0: SE of mu0
mu1: Mean survival time for trt1
se1: SE of mu1
delta: Difference between mu0 and mu1
se_d: SE of delta

Examples


data("oak")
tau <- 26
time <- oak$OS
status <- oak$os.status
trt <- oak$trt
covariates <- oak[, c("btmb", "pdl1")]
results <- rmst_unadjust(time, status, trt, tau)
