Paired T-tests were conducted on the time series values of each index among the four storage temperature groups, and a logistic growth curve function model was established. The results showed that there were extremely significant differences between various ...
基于Logistic 增长曲线模型的大学在校学生数量发展预测 彭怀祖 (南通大学,江苏南通226007)摘要:由1983-2009年高等教育在校学生数的增长趋势图可以发现,我国高等教育规模发展表现为一种“S ”形增长,为此构建logistic 增长曲线模型,并结合1983-2009年数据对未来10年我国高等教育在校学生数进行预测。预测结果略高于《...
Notwithstanding this limitation the logistic growth equation has been used to model many diverse biological systems. Carlson [2] reported the growth of yeast which is modelled well by the curve [3], [4]. Morgan [5] ingeniously used the equation to describe herding behaviour of African elephants...
The logistic growth definition in population models refers to the gradual growth of the population in the beginning and then increases when the number of people grows. When does logistic growth occur? According to the logistic growth model, the population grows the most when a high number of peo...

2. Logistic Growth (S-curves) The classic change model is the sigmoid function, or S-curve, given this name due to its shape. It is also called the Gompertz curve, after the mathematician who first discovered it in natural systems. Logistic growth may be the best-known example of S-curv...
A variety of growth curves have been developed to model both unpredated, intraspecific population dynamics and more general biological growth. Most predictive models are shown to be based on variations of the classical Verhulst logistic growth equation. We review and compare several such models and ...
