摘要
把逐差法组织成对差法,并以自变量差值平方为权系数进行加权平均来计算比例系数。利用初等数学方法证明了所选权函数的最优性。
The seriatim subtraction form is reorganized tional coefficient is estimated by weighted averaging differences being the weight coefficients. Its optimality ry mathematics. into the symmetrical subtraction form, and the propor- the symmetrical subtraction with the squared argument of the selected weight coefficients is proved by elementa-
