A printed summary containing the formula, data name, converged parameters, vertical residual sum-of-squares $$\sum_{i=1}^{n}(y_i - \hat{y_i})^2$$, orthogonal residual sum-of-squares $$\sum_{i=1}^{n}\| D_i \|^2$$, number of points with orthogonality as obtained from check_o
and number of iterations to convergence.
