The seriatim subtraction form is reorganized into the symmetrical subtraction form,and the propor-tional coefficient is estimated by weighted averaging the symmetrical subtraction with the squared argument differences being the weight coefficients. Its optimality of the selected weight coefficients is proved by elementa-ry mathematics.
