Re: [Question #176228]: Rolling Standard Deviation for N samples triggers UnboundLocalError in specific cases

 

Question #176228 on Graphite changed:
https://answers.launchpad.net/graphite/+question/176228

    Status: Open => Needs information

Nicholas Leskiw requested more information:
Heh, then don't do that.  ; )

I think throwing an error is the appropriate course of action here don't
you?  You can't really get the standard deviation of a set that contains
null values, can you?  What would you do for a metric that has values,
is null for a bit, has a few more, is null for a bit, has more values?

Seriously, some one with a math degree comment on this, I almost flunked
Calc 3 and Linear Algebra...
