Long day today. Seven straight hours of class.

Rucker went crazy today in Work Design, threw out a whole new way of looking at statistics. It was mind-blowing to say the least. It seemed a bit scattered and unorganized, but it didn't help that we weren't up to speed with our linear algebra skills.

It's a geometric view of stats, where you use design spaces and error spaces and vectors.

Imagine, if you made 50 observations, you'd have a 50-dimensional space. And 48 or 49 of those dimensions would be error space, which translate, in traditional statistics, to degrees of freedom.

And it gets worse from there.
