Ask HN: Please review my most recent side project (cost behavior analysis)

by hoop on 11/6/2010, 5:34 PM with 4 comments

I made this web app because I found doing cost behavior analysis for my managerial accounting homework very tedious and relatively time-consuming.

Cost behavior analysis is the process of dividing a mixed cost into its variable and fixed components (math: Finding the slope and y-intercept of a line or "m" and "b" in the equation y = mx + b)

This app is written in Python on the Tornado framework and makes use of numpy, matplotlib, and MongoDB.

What can I do to make this app easier to use and more useful?
