Richards模型与Logistic模型在人口预测中的比较
Co mparison of Richards Model and Logistic Model in Population Prediction
摘要
Abstract
Logistic model is a commonly used population prediction model,and a nonlinear s-type growth model containing four parameters,Richards model,is obtained by adding a parameter to Logistic model.Chinese population during 1985—2014 is predicted by Logistic model and Richards model respectively,and the population prediction model is constructed.By comparing with the real population,the results show that Richards model is better than Logistic model in fitting effect.关键词
