KruskalWallisTest Class

Members See Also 
Represents the Kruskal-Wallis test.

Namespace: Extreme.Statistics.Tests
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 5.0.13017.0 (5.0.13248.0)

Syntax

C#
public sealed class KruskalWallisTest : MultiSampleTest
Visual Basic
Public NotInheritable Class KruskalWallisTest
	Inherits MultiSampleTest
Visual C++
public ref class KruskalWallisTest sealed : public MultiSampleTest
F#
[<SealedAttribute>]
type KruskalWallisTest =  
    class
        inherit MultiSampleTest
    end

Remarks

Use the KruskalWallisTest class to test whether a number of samples come from the same population. This test can be thought of as a non-parametric variation of one-way analysis of variance that doesn't assume the data is normally distributed.

This class approximates the distribution of the test statistic by a beta distribution. This approximation has been found to be more accurate than the traditional chi-square approximation. Still, for small sample sizes, critical values and tail probabilities may differ significantly from their exact values.
