jStat – JavaScript Statistical Library

Mufti Ali — Sat, 19 Mar 2011 03:45:38 +0000

jStat is a statistical library written in JavaScript that allows you to perform advanced statistical operations without the need of a dedicated statistical language (i.e. MATLAB or R). The majority of jStat functions can be used independently of any other libraries. However, the plotting functionality of jStat is based on the jQuery plugin – flot.

jStat only uses elements that adhere to the jQuery UI ThemeRoller styles so any jQuery UI theme can be used. jStat uses numerous advanced statistical functions that require considerable processing power. This requirement results in differing user experiences depending upon your browser choice. Currently, the fastest browser is Google Chrome. jStat should work in all major browsers. Most of the limitations arise from the use of the HTML 5 canvas element when plotting.

Requirements: jQuery Framework, Flot
