摘要
以往关于生物种群增长的数学模型多是用微分方程和概率极限定理的方法来推导的。本文改用回归分析 ,系数显著性检验和残差检验的方法 ,直接从统计数字出发 ,得出美国人口在1880— 1960年的人口数字增长模型——正态前升模型。它是拟合得很好的不同以往的模型。并给出了初步的解释。
Differential equation and probability limit theorem have been widely used in the mathematical model of biological population growth.In this paper,directly from data,we use regression analysis,significant test of regression coefficients and residual analysis to get the model of increasing American population(from 1880 to 1960)_Normal Pre-ascending model.It is a fitting model which is better than others before.In this paper,we also give a preliminary explanation.
