Least-squares solution of the modeling approach

 Solving for the model ${\bf m}$ in the modeling approach requires the inversion of a $2\times2$ block matrix. I derive the basic steps of this procedure in the following section. Then I derive the least-squares inverse of ${\bf m}$ in equation ([*]). Finally, I give a geometric interpretation of the least-squares inverse.
