Question:
=+As described in Section 3.5, the minimization requires taking k 1 1 partial derivatives, equating these to zero to obtain a system of linear equations (the normal equations), and solving this system for the estimates. There are formulas for the least squares estimates, but the only sensible way to express them is to use the branch of mathematics called matrix algebra. Fortunately, this is not necessary for our purposes; these formulas have
