| Aug 26, 2014 at 13:12 | comment | added | whuber♦ | @Caracal Thank you for the references. I originally envisioned an answer that uses diagrams like those in your answer--which make a wonderful supplement to my answer here--but after creating them felt that pseudo-3D figures might be too complex and ambiguous to be entirely suitable. I was pleased to find that the argument could be reduced entirely to the simplest vector operations in the plane. It may also be worth pointing out that a preliminary centering of the data is unnecessary, because that is handled by including a nonzero constant vector among the $x_i$. | |
