一种 Logistic 模型参数估计的新方法及应用
New Method of Logistic Model Parameter Estimation and Application
摘要
Abstract
This paper presened a new method of logistic growth curve for parameter estimation,which uses the cubic spline interpolation functions instead of growth curve in the derivative value,and then uses the least squares estimation method to derive the parameters.And the instance analysis and verification show that.the proposed approach can get the higher fitting precision.than the average of three point method to estimate the c and the linear regression estimate the parameter values of b and c .关键词
