pp.kSamples {kSamples}

Upper Tail Probability Plots for Objects of Class kSamples

Description

This function plots upper tail probabilities of the limiting distribution against the corresponding exact or simulated probabilities, both on a log-scale.

Usage

pp.kSamples(x) 

Arguments

x

an object of class kSamples

Details

Objects of class kSamples are produced by any of the following functions

ad.test Anderson-Darling k-sample test.

ad.test.combined Combined Anderson-Darling k-sample tests.

qn.test QN rank scores test.

qn.test.combined Combined QN rank scores tests.

contingency2xt test for 2 * t contingency table.

contingency2xt.comb test for the combination of 2 * t contingency tables.

jt.test Jonckheere-Terpstra test.

Steel.test Steel test. This will work only for alternative = "greater" or "two-sided". The approximation quality for "less" is the same as for "greater".

The command pp.kSamples(x) for an object of class kSamples will only produce a plot when the object x contains non-NULL entries for the null distribution. The purpose of this function is to give the user a sense of the asymptotic distribution accuracy.
