运用改进单纯形法拟合Logistic曲线的研究

Ｌｏｇｉｓｔｉｃ方程是研究有限空间内种群增长规律的重要工具之一本文运用改进单纯形法最优拟合Ｌｏｇｉｓｔｉｃ曲线，结果表明改进单纯形法具有较强的拟合非线性方程的能力，对生物实验及生态、生理学中诸多非线性曲线的参数估计具有普遍意义．

A Study of Optimum Fitting Logistic Curve by Modified Simplex Method

Logistic equation is one of the most important tools for the study on species growth regularity in limited space. In this paper, modified simplex mothod is used to determine the values of parameters in logistic equation that will give the best least-squares fit to a set of data, the results show that modified simplex mothod has strong ability for fitting non-linear equations, and therefore it may have a wider use in determining the values of parameters of non-linear curve in the field of ecology and physiology.
