【摘要】：將多元加權(quán)總體最小二乘模型進(jìn)行變換,轉(zhuǎn)化為加權(quán)總體最小二乘模型,推導(dǎo)構(gòu)造新的系數(shù)矩陣和系數(shù)矩陣元素協(xié)因數(shù)陣的公式,研究多元加權(quán)總體最小二乘的解算流程。以Jazaeri加權(quán)總體最小二乘為例,給出多元總體最小二乘參數(shù)的解算過程。通過算例分析和比較,驗(yàn)證了該方法的有效性。
[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.
