Check out this website I created that uses an EViews-like interface and syntax to do OLS regression!
Free Linear Regression
I couldn't find any other decent websites that do multiple linear regression and I wanted something for myself that can test hypotheses, and be able to display multiple figures beside each other for comparison - all without having to buy or download a pirated stat package.
I built it for people like me who don't want to have to walk all the way to the school library in the snow just to use STATA.
Let me know what you think!
