逻辑斯谛曲线参数的一种数值估测方法
A Numerical Method for Estimating the Parameters of the Logistic Equation
-
摘要: 本文提出了逻辑斯谛曲线的参数K、r、a的一种数值估测方法。它是基于数值积分和矩阵最小二乘法的数值方法。算例表明,本法计算简便,并能满足原始数据的初始条件。这一点,却往往是其他方法难以做到的。Abstract: A numerical method for estimating the parameters K, r, a of the Logistic curve is presented. It is based on the numerical integration and matrix least square method. The result shows that this method is simple and straightward, and fulfills the observed initial-value while the other methods are difficult to do so.
