UnivariatePopulationVariance Method

Estimates of the variance of the underlying population.

Namespace: Meta.Numerics.Statistics
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.2.0+6d77d64445f7d5d91b12e331399c4362ecb25333

C#

public static UncertainValue PopulationVariance(
	this IReadOnlyCollection<double> sample
)

VB

<ExtensionAttribute>
Public Shared Function PopulationVariance ( 
	sample As IReadOnlyCollection(Of Double)
) As UncertainValue

C++

public:
[ExtensionAttribute]
static UncertainValue PopulationVariance(
	IReadOnlyCollection<double>^ sample
)

F#

[<ExtensionAttribute>]
static member PopulationVariance : 
        sample : IReadOnlyCollection<float> -> UncertainValue

Parameters

sample IReadOnlyCollectionDouble: The sample.

Return Value

UncertainValue
An estimate, with uncertainty, of the variance of the distribution from which the sample was drawn.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadOnlyCollectionDouble. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

In contrast to the Variance(IReadOnlyCollectionDouble) method, this method estimates the variance of the underlying population from which the sample was drawn, and provides a error estimate for that value.

Exceptions

ArgumentNullException	sample is .
InsufficientDataException	sample contains fewer than 3 values.
