        values : Vector<'T> * 
        weights : Vector<'T> -> float

Double
The mean of the variable weighted by weights.

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

If weights is null, the unweighted mean is returned.

ArgumentNullException	values is null.
DimensionMismatchException	The length of weights does not equal the number of observations of the variable.
