summary.nparttest: Summary of npar.t.test

Description

The function summary.npar.t.test produces a result summary of npar.t.test. It can only be applied to objects of class "nparttest".

Usage

# S3 method for nparttest
summary(object,...)

Arguments

object

An object of class "nparttest", i.e. the result when applying npar.t.test to a dataset. Otherwise an error will occur.

...

Arguments to be passed to methods.

Value

The function produces a summary of the result of npar.t.test starting with some global information: alternative hypothesis, confidence level, interpretation. This is followed by:

Info

List of samples and sample sizes.

Analysis

Effect: relative effect p(a,b) of the two samples 'a' and 'b', Estimator: estimated relative effect, Lower: Lower limit of the confidence interval, Upper: Upper limit of the confidence interval, T: teststatistic p.Value: p-value for the hypothesis by the choosen approximation method.

Permutation_Test

Result of the studentized permutation test.

Details

Since summary.nparttest is a S3 method it suffices to use summary(x) as long as x is of class "nparttest". It will be interpreted as summary.nparttest(x).
