Ever wonder how regression works?


Click around and use the arrow keys. The above is a program, not an image. Please, no wagering.

Back when the DSN editor was a student at Chicago, he learned Statistics and History of Statistics from Steve Stigler, who proposed a visual demonstration of least squares regression. Together they came out with a now-obsolete Mac version. Today, DSN is proud to announce a version that will run on any browser that does Flash.

The demonstration should be self-explanatory to anyone who understands simple regression, and if not, might suffice as a tutor. And if not, there is always the linear regression article in Wikipedia.


Can I use this to teach my class?

Yes, and please let us know how it goes! A benefit of the web-based version is that it can be reached from any place with a Web connection.
