| NMathFunctionsWeightedVariance(Double, Double, Boolean) Method |
Calculates the weighted variance of the given data.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static double WeightedVariance(
double[] data,
double[] weights,
bool normalizeWeights
)
Public Shared Function WeightedVariance (
data As Double(),
weights As Double(),
normalizeWeights As Boolean
) As Double
public:
static double WeightedVariance(
array<double>^ data,
array<double>^ weights,
bool normalizeWeights
)
static member WeightedVariance :
data : float[] *
weights : float[] *
normalizeWeights : bool -> float
Parameters
- data Double
- The data.
- weights Double
- The weights.
- normalizeWeights Boolean
-
If true, normalize the weights to sum to the length of the data array. If the weights
represent sampling (reliability) weights, normalizing is usually appropriate. But if the weights
represent frequency counts, which in effect expand the data array by these counts, do not normalize.
Return Value
DoubleThe weighted variance.
