Richards模型参数估计及其模型应用

在非线性模型中,Richards模型是一个含有四参数的增长曲线模型,该模型对数据的拟合有较强的适应性,应用较为广泛.但其参数的估计较为复杂,给出简便易行的三种方法,实例应用表明拟合效果很好.

Parameter Estimation of Richards Model and Its Application

Richards model is four parameters growth curve model in non-linear model,this model have strong adaptability about data fitting and rather abroad application.but parameter estimation of model is relatively complex,this paper give three method of simple and feasible,the example indicate that fitting effect is very good.
