BivariateCovariance Method

Computes the covariance of the two variables.

Namespace: Meta.Numerics.Statistics
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4

Syntax

public static double Covariance(
	this IReadOnlyList<double> x,
	IReadOnlyList<double> y
)

<ExtensionAttribute>
Public Shared Function Covariance ( 
	x As IReadOnlyList(Of Double),
	y As IReadOnlyList(Of Double)
) As Double

public:
[ExtensionAttribute]
static double Covariance(
	IReadOnlyList<double>^ x, 
	IReadOnlyList<double>^ y
)

[<ExtensionAttribute>]
static member Covariance : 
        x : IReadOnlyList<float> * 
        y : IReadOnlyList<float> -> float

x: Type: System.Collections.GenericIReadOnlyListDouble
The values of the first variable.
y: Type: System.Collections.GenericIReadOnlyListDouble
The values of the second variable.

Type: Double
The covariance between the two variables.

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadOnlyListDouble. 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).

Exceptions

Exception	Condition
ArgumentNullException	x or y is .
DimensionMismatchException	x and y do not contain the same number of entries.
InsufficientDataException	There are fewer than two entries in the sample.
