The [http://en.wikipedia.org/wiki/Ordinary_least_squares#Example_with_real_data example] on WP happens to be a polynomial regression example, and so code from the [[Polynomial regression]] task can be reused here. The only difference here is that givens x and y are computed in a separate function as a task prerequisite.
