非线性回归问题的迭代法在地下水动态研究中的应用

Iteration method of nonlinear regression and its application to ground water studies

本文介绍了非线性回归问题迭代法的教学分析原理，解决了不能用最小二乘法求解的纯非线性回归问题．在地下水研究中应用结果表明：该方法快捷、方便，且计算精度较高，可在微机上实现．

The mathematical principle of using iteration method to solve the nonlinear regression problem is discussed in this paper. The pure nonlinear regression problem can not be solved by minimum double multiplication. The iteration method is applied to study on ground water. Results show that the method is easy for use and yields high precision.
