Calculates the biased variance of the vector elements that are not equal to NaN.

Namespace:  CenterSpace.NMath.Core
Assembly:  NMath (in NMath.dll) Version: 5.1.0.0

Syntax

C#
public static float NaNVariance(
	FloatVector v
)
Visual Basic (Declaration)
Public Shared Function NaNVariance ( _
	v As FloatVector _
) As Single
Visual C++
public:
static float NaNVariance(
	FloatVector^ v
)

Parameters

v
Type: CenterSpace.NMath.Core..::.FloatVector
A vector.

Return Value

The biased variance of the elements in v that are not NaN.

Remarks

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

Exceptions

ExceptionCondition
CenterSpace.NMath.Core..::.InvalidArgumentException Thrown if v has zero length.
