Bootstrap CI for dynamic RMST delta curve

Description

Bootstrap CI for dynamic RMST delta curve

Usage

boot_rmst_delta(xA, xB, R = 300, conf = 0.95, seed = NULL)

Arguments

`xA`	A `survmat` object for arm A.
`xB`	A `survmat` object for arm B.
`R`	Number of bootstrap replicates.
`conf`	Confidence level in `⁠(0, 1)⁠`.
`seed`	Optional RNG seed.

Value

A list with point estimate and percentile confidence bands.

Examples

time <- c(0, 1, 2)
xA <- as_survmat(rbind(c(1.0, 0.9, 0.7), c(1.0, 0.8, 0.6)), time, group = c("A", "A"))
xB <- as_survmat(rbind(c(1.0, 0.95, 0.8), c(1.0, 0.85, 0.7)), time, group = c("B", "B"))
boot <- boot_rmst_delta(xA, xB, R = 10, seed = 1)
boot$estimate
