I am looking for a JavaScript
or a PHP
library to calculate common business/statistical metrics (e.g. Total
, Avg
, YTD
, YoY
, MoM
, CAGR
growth, standard deviation, regression line coordinates) from simple arrays/objects with a structure such as:
The idea is that I would just provide the arrays with some basic parameters (e.g. time period I'm interested in) and would get all the numbers crunched automatically in return.
Can anybody point me to a library they've used and trust from experience?
