KhmaladzeFormat: Khmaladze Test

In Qtools: Utilities for Quantiles

Khmaladze Test

Description

This function provides significance levels of the Khmaladze Test using a (hard-coded) table of asymptotic critical values.

Usage

KhmaladzeFormat(object, epsilon)

Arguments

object	an object of class "KhmaladzeTest".
epsilon	trimming value. One of c(0.05,0.10,0.15,0.20,0.25,0.30).

Details

This function is applied to an object produced by KhmaladzeTest. The Khmaladze test is used to test for location–shift and location-scale–shift hypotheses (Koenker, 2005). The test statistic is computed over the interval [epsilon, 1 - epsilon], where epsilon is the trimming value.
