非线性模型在海西州地区肾炎发病情况中的应用

基于可线性化的非线性模型理论,通过建立不同的数学模型,研究每月汉族肾炎发病人数与总肾炎发病人数之间的关系。文章通过EV iews软件对青海海西州地区肾炎发病例监测登记资料进行统计分析,同时进行非线性模型拟合,观察汉族肾炎发病人数与总肾炎发病人数之间的发展趋势,选择最优的数学模型,建立了可线性化的非线性模型,并进行了实际值与预测值比较。

Application of Non- linear Model Based on Nephritis Morbidity Situation in Haixizhou Region

Based on the theory of non - linear model which can be translated into linear model, different kinds of mathematical models had been established to study the relationship between the number of the Hart nationality＇s nephritis and the total number of the nephritis each month. In this paper, EViews software for the nephritis in Haixizhou region Qinghai was used to monitor cases of the registration data for statistical analysis, at the same time the model was fitted to observe the development trend between the number of the Han nationality~ nephritis and the total number of the nephritis, the best mathematical model was seleeted, the non -linear model was established and the actual value and predicted value was compared.
