Comment (by kumanna):

 Dear Robert,

 Maybe I wasn't being clear enough. What I would like to request you to
 implement is the definition given here:

 http://en.wikipedia.org/wiki/Variance#Generalizations

 In my opinion, this is what is done in most cases, and in most signal
 processing books. I'll try to give you some evidence if this is not
 convincing enough.

 Thanks!

 Kumar
