【摘要】：将多元加权总体最小二乘模型进行变换,转化为加权总体最小二乘模型,推导构造新的系数矩阵和系数矩阵元素协因数阵的公式,研究多元加权总体最小二乘的解算流程。以Jazaeri加权总体最小二乘为例,给出多元总体最小二乘参数的解算过程。通过算例分析和比较,验证了该方法的有效性。
[Abstract]:The multivariate weighted population least squares model is transformed into the weighted population least squares model, and the formulas for constructing a new coefficient matrix and a cofactor matrix of coefficient matrix elements are derived. The process of solving multivariate weighted population least squares is studied. Taking Jazaeri weighted population least squares as an example, the calculation process of multivariate population least squares parameters is given. The effectiveness of this method is verified by example analysis and comparison.
