摘要
研究产生Logistic曲线的Logistic微分方程,给定显著性水平α,利用微分与差分基本原理,在置信度1-α下借助多元回归估计Logistic曲线参数.最后应用Logistic曲线研究中国1990-2007的人口数,预测得到中国2008年的人口数约为13.24亿.
Research Logistic differential equation which generates Logistic curve, given a significance level α, estimate Logistic curve parameters at 1 - α confidence level via multi - regression by making use of the basic principle of differential and difference ,finally, apply Logistic curve to describe China populations data from 1990 to 2007, obtains that forecast data of Chinese population in 2008 is approximately 13.24 billion.
