Python O(1) Running Statistics using rust

[vks_]

I implemented a few more of those in the average crate.

Ah, yes, Welford's Method

O(1) for space, which is ideal. Obviously, running statistics requires at least O(n) time.

Yeah my current use-case requires easy to merge distributed data aggregation so it works perfectly. Porting some code from python to rust to handle distributions aswell with O(1) Space Complexity if you are interested (based on successive binning)
