VectorExtensions.ExtrapolatedPercentChange Method

Returns a vector whose observations are the extrapolated percentage change of the observations over the specified lag.

public static Vector<double> ExtrapolatedPercentChange(
	this Vector<double> vector,
	int lag,
	double length
)

Visual Basic

<ExtensionAttribute>
Public Shared Function ExtrapolatedPercentChange ( 
	vector As Vector(Of Double),
	lag As Integer,
	length As Double
) As Vector(Of Double)

C++/CLI

public:
[ExtensionAttribute]
static Vector<double>^ ExtrapolatedPercentChange(
	Vector<double>^ vector, 
	int lag, 
	double length
)

[<ExtensionAttribute>]
static member ExtrapolatedPercentChange : 
        vector : Vector<float> * 
        lag : int * 
        length : float -> Vector<float>

Parameters

vector Vector<Double>: The vector to transform.
lag Int32: An integer larger than zero that specifies the distance between the current observation and the reference observation.
length Double: The number of periods over which to extrapolate the growth rate.

Return Value

Vector<Double>
A vector.

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 growth rate is the percentage change between quantities over time. The extrapolated growth rate states the growth rate extrapolated over the specified number of periods.

The new vector gets the name extChangePct<n>(<name>), where <name> is the name of the original vector and <n> . is the length.

Exceptions

ArgumentOutOfRangeException

lag is less than or equal to zero.
