rro - Running Regression Objects

The rro allows conversion to calculate slope, intercept, and correlation on (X,Y).

This object does not require RAM for the samples.

See: float.regr
See: https://www.johndcook.com/blog/running_regression/

local mo = float.regr()
local t = {5,8,4,5}
mo:push(2,5)
mo:push(6,1)
mo:push(t)
print(mo:get()) -- -0.54,7.06,-0.32,4

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

local mo = float.regr()
local t = {5,8,4,5}
print(mo:push(2,5):push(6,1):push(t):get()) -- -0.54,7.06,-0.32,4
