In confintr: Confidence Intervals

CI for the IQR

Description

This function calculates bootstrap CIs (by default "bca") for the population interquartile range (IQR), i.e., the difference between first and third quartile.

Usage

ci_IQR(
  x,
  probs = c(0.025, 0.975),
  type = "bootstrap",
  boot_type = c("bca", "perc", "norm", "basic"),
  R = 9999L,
  seed = NULL,
  ...
)

Arguments

x	A numeric vector.
probs	Lower and upper probabilities, by default c(0.025, 0.975).
type	Type of CI. Currently not used as the only type is "bootstrap".
boot_type	Type of bootstrap CI c("bca", "perc", "norm", "basic").
R	The number of bootstrap resamples. Only used for type = "bootstrap".
seed	An integer random seed. Only used for type = "bootstrap".
...	Further arguments passed to boot::boot().

Value

An object of class "cint", see ci_mean() for details.

Examples

x <- rnorm(100)
ci_IQR(x, R = 999)  # Use larger R
