摘要
较详细地分析了几种增长与衰减模型,对参数取何值时模型为单增或单减,通过导数加以说明,并确定了模型在无穷大时的趋势及参数如何估计的方法.
Some of growth models and attenuate models are given a minute analyse in this paper,the increase and decrease of models are given a illustrate with change of parameter after derivative analyse,the change trend of models on infinitly and the parameter estimation metheds are discussed in detail.
