NMathFunctionsVariance(FloatComplexVector) Method

Calculates the biased variance of a given vector.

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

Syntax

public static FloatComplex Variance(
	FloatComplexVector v
)

Public Shared Function Variance ( 
	v As FloatComplexVector
) As FloatComplex

public:
static FloatComplex Variance(
	FloatComplexVector^ v
)

static member Variance : 
        v : FloatComplexVector -> FloatComplex

Exceptions

Exception	Condition
InvalidArgumentException	Thrown if v has zero length.

Remarks

variance = (NMathFunctions.pow(v[0] - mean, 2) + NMathFunctions.pow(v[1] - mean, 2)) / n
