摘要
为了拟合带有2个参数的一元非线性回归模型,提出了一种ExcelVBA程序算法。该算法根据"残差平方和最小"原则通过建立关于参数的For循环语句并利用最小值传递的思想,从而获得一元非线性回归模型的参数值。实例证明该算法简单实用。
In order to fit unitary non-linearity regress equation with two parameters, a VBA programmed algorithm was proposed. The method proposed acquired parameters of unitary non-linearity regress equation through setting up for statement and utilizing the function of minimum value transmission according to the principle of ＇minimum sum of squared residuals~. The example showed that the method of fitting unitary non-linearity regress equation was not only simple and practical, but also higher in accuracy.
