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

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.

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).

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

lag is less than or equal to zero.
