WilcoxonSignedRankTestComputeExactPValue Method

Computes an exact p-value by enumerating all possible rank sums.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public static double ComputeExactPValue(
	double statistic,
	int n
)

Public Shared Function ComputeExactPValue ( 
	statistic As Double,
	n As Integer
) As Double

public:
static double ComputeExactPValue(
	double statistic, 
	int n
)

static member ComputeExactPValue : 
        statistic : float * 
        n : int -> float

Parameters

statistic Double: The test statistic.
n Int32: The sample size.

Return Value

Double

Remarks

All 2^n possible distributions of signs over ranks are generated as bit-patterns. The algorithm is adapted from http://www.fon.hum.uva.nl/Service/Statistics/Signed_Rank_Algorihms.html#C.
Equivalent to the R psignrank() method.
