Web188 any orthogonal property exists among errors. Since the least squares method concentrates only on minimizing 189 the sum of squares of deviations of the observations from the expected values, it is not an appropriate method 190 as a tool for getting the information on an orthogonal property between the groups of errors. The orthogonal Web$$\begin{aligned}&D^2_{(y,v)}{\mathcal {L}}_0({{\bar{y}}}, {{\bar{v}}}, {{\bar{\psi }}}, {{\bar{w}}})[(y, v), (y, v)]\\&\quad =\int _\Omega \big [(\phi _{yy}[x ...
