three-stage least squares method

Therefore, three modified Newton approaches, the Parameter Newton method, the Damping Newton method and the Least Squares method, were used to solve the nonlinear chemical equilibrium equations for a case where the classical Newton method failed.

针对经典Newton法求解失效的具体情况，考虑几种措施（参数Newton法、阻尼Newton法及最小二乘法）改进原有的方法以求得非线性方程组的数值解，从而保证模拟顺利进行。

At present, the Methods: Used have least-squares method, Kalman filtering method and three-probe method.

目前, 经常采用的方法有最小二乘法 、 卡尔曼滤波法和三传感器法等.此处研究这些方法的缺陷.

基于约束最小二乘法的变压器三相漏感辨识算法

Through three examples: Spheroidal Earth, the Isostatic Earth, the Least Squares Method, this article give a simple discussion that the hypothesis promotes the development of survey greatly.

以地扁说、地壳均衡学说、最小二乘法等为例的假说在测绘科学发展中具有一定的作用和意义。
