逻辑斯谛模型的递归分析与拟合

THE RECURSIVE ANALYSIS AND FITTING OF LOGISTIC MODELS

对逻辑斯谛模型进行了递归分析，得到递归公式．该式不仅为模型辨识提供了统计检验方法，而且可用于估计逻辑斯谛模型的二个重要参数：环境载力Ｋ和内禀增长率ｒ．用递归分析法拟合逻辑斯谛模型具有方法合理、计算简便和通用性强的优点．

The recursion formula[N(t+s)]-1=α+β·[N(t)]-1 of Logistic models is derived from recursive analysi..The formula can be used as a statistical method of identification of those models and the estimates of two important parameters(i.e.carrying capacity Kand intrinsic growth rate r) are obtained as a result of it. It is a reasonable method of fitting Logistic models and is simple in calculation.
