Syntax

public static double WeightedStandardDeviation(
	double[] data,
	double[] weights,
	bool normalize
)

Public Shared Function WeightedStandardDeviation ( 
	data As Double(),
	weights As Double(),
	normalize As Boolean
) As Double

public:
static double WeightedStandardDeviation(
	array<double>^ data, 
	array<double>^ weights, 
	bool normalize
)

static member WeightedStandardDeviation : 
        data : float[] * 
        weights : float[] * 
        normalize : bool -> float

data Double: The data.
weights Double: The weights.
normalize 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 vector by these counts, do not normalize.

Double
The weighted standard deviation.

Exceptions

Exception	Condition
MismatchedSizeException	Thrown if data and weights do not have the same length.
