rso - Running Statistics Object

The rso allows statistics to be calculated on-the-fly for samples.
This object does not require RAM for the samples.

See: float.stat
See: https://www.johndcook.com/blog/skewness_kurtosis/

local mo = float.stat()
local t = {5,8,4,5}
mo:push(2,5,6)
mo:push(1)
mo:push(t)
print(mo:get()) -- 4.25,5.07,2.25,0.15,-0.79,8

Because many methods return the object itself you can chain calls:

local mo = float.stat()
local t = {5,8,4,5}
print(mo:push(2,5,6):push(1):push(t):get()) -- 4.25,5.07,2.25,0.15,-0.79,8
