ci_median_diff: CI for the Population Median Difference of two Samples

Description

This function calculates bootstrap CIs for the population value of median(x) - median(y) by calling ci_quantile_diff(, q = 0.5). See ci_quantile_diff for details.

Usage

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

Value

An object of class "cint" containing these components:

• parameter: Parameter specification.

• interval: CI for the parameter.

• estimate: Parameter estimate.

• probs: Lower and upper probabilities.

• type: Type of interval.

• info: Additional description.

Arguments

x

A numeric vector.

y

A numeric vector.

probs

Lower and upper probabilities, by default c(0.025, 0.975).

type

Type of CI. Currently, "bootstrap" is the only option.

boot_type

Type of bootstrap CI ("bca", "perc", "norm", "basic").

R

The number of bootstrap resamples.

seed

An integer random seed.

...

Further arguments passed to boot::boot().
