Stats.CoefficientOfVariation Method

Gets the coefficient of variation of a variable, if it exists.

Definition

Namespace: Extreme.Statistics
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23

public static double CoefficientOfVariation(
	this Vector<double> values
)

Visual Basic

<ExtensionAttribute>
Public Shared Function CoefficientOfVariation ( 
	values As Vector(Of Double)
) As Double

C++/CLI

public:
[ExtensionAttribute]
static double CoefficientOfVariation(
	Vector<double>^ values
)

[<ExtensionAttribute>]
static member CoefficientOfVariation : 
        values : Vector<float> -> float

Parameters

values Vector<Double>

Field Value

Double
The coefficient of variation of the variable, if it exists; otherwise NaN.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Vector<Double>. 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

The coefficient of variation is the ratio of the StandardDeviation<T>(Vector<T>) to the Mean<T>(Vector<T>). If the mean is zero, the coefficient of variation is undefined. It gives an indication of the variability of the observations relative to their size.
