农业生产中四组数据的Logistic模型的参数确定

Parameter determination of Logistic Model for Four Data Sets in Agricultural Production

本文介绍了求非线性回归模型参数的基本理论,选择Logistic回归模型作为模型函数.以牧草再生长的数据集1为例,用Mathematica软件绘制了数据集1的点图.最后给出四组数据的拟合曲线和置信域.

In this paper,the basic theory is introduced for the sake of the parameters of nonlinear regression models,Logistic regression model can be used as a model function,the use of the data set of pasture regrowth,the point figure of the data set is drawn by the Mathematica software.The last,fit curves and confidence domain is given for four sets of data.
