Native bootstrap confidence intervals — morie_boot

Reproduces boot::boot.ci for the "norm", "basic", "perc" and "bca" interval types (BCa via the regression empirical-influence estimate, matching boot's default).

Usage

morie_boot_ci(
  boot_obj,
  conf = 0.95,
  type = c("perc", "norm", "basic", "bca"),
  index = 1L
)

Arguments

boot_obj: A morie_boot object from morie_boot().
conf: Confidence level (default 0.95).
type: Character vector: any of "perc", "norm", "basic", "bca".
index: Which column of t to summarise (default 1).

Value

Named list; each element is c(lower, upper).
