UnivariateMannWhitneyTest Method

public static TestResult MannWhitneyTest(
	IReadOnlyList<double> a,
	IReadOnlyList<double> b
)

Public Shared Function MannWhitneyTest ( 
	a As IReadOnlyList(Of Double),
	b As IReadOnlyList(Of Double)
) As TestResult

public:
static TestResult^ MannWhitneyTest(
	IReadOnlyList<double>^ a, 
	IReadOnlyList<double>^ b
)

static member MannWhitneyTest : 
        a : IReadOnlyList<float> * 
        b : IReadOnlyList<float> -> TestResult 

Parameters

a  IReadOnlyListDouble

The first sample.

b  IReadOnlyListDouble

The second sample.

Return Value

The Mann-Whitney test is a non-parametric alternative to Student's t-test (StudentTTest(IReadOnlyCollectionDouble, IReadOnlyCollectionDouble)). Essentially, it supposes that the medians of the two samples are equal and tests the likelihood of this null hypothesis. Unlike the t-test, it does not assume that the sample distributions are normal.
