One-sample percentile bootstrap

Description

Tests whether a robust location measure (median, Huber Psi) differs from a null value and reports a 95% confidence interval based on percentile bootstrap.

Usage

onesampb(x, est = "onestep", nboot = 2000, nv = 0)

Arguments

x

a numeric vector.

est

robust estimator to be used ("onestep", "mom", or "median").

nboot

number of bootstrap samples.

nv

value under H0.

Value

Returns an object of class "onesampb" containing:

ci

95% confidence interval

estimate

p.value

p-value

n

number of effective observations

call
