摘要
在回归分析中,有必要讨论同时顾及自变量和因变量误差的回归计算。在总体最小二乘原则下,从公式上导出了3种解算方法,为条件平差、间接平差和两步解算算法。通过矩阵运算,从理论上证明了3种解算算法的等价性,可保证解算结果的一致性。
In regression analysis,there is a need to discuss taking into account the independent variables and the dependent variable error of the regression calculation. In the total least-squares principle, this paper is derived from the formula of the three kinds of solution method for the condition of adjustment ,indirect adjustment and two-step solution algorithm. It is proved that three kinds of equivalence solution algorithm in theory using the matrix operations, so that can guarantee the consistency of the results of solution.
