【摘要】 研究GDP等社会经济指标与传染病发病率之间的相关性具有重要的意义。建立多元线性回归模型,采集GDP、每千人卫生技术人员数目等六类指标,以及2008年分省区的传染病发病人数,针对以上数据进行量性分析。采用SPSS软件,通过后退法首先排除掉那些影响较小的变量,然后利用显著性检验,建立合适的模型,结果表明,染病人数只与GDP与各省人口有关系,与GDP成反比,与各省人口成正比(即发病率与GDP成反比)。验证的模型是一个有效的模型,具有预测性。更多还原

【Abstract】 It is necessary to study the correlation between GDP and infectious diseases. To build multivariate linear regression model,gather six indices of GDP data,number of per thousand health workers,as well as the number of infectious diseases in the year of 2008 for provinces. According to the above data,this study deals with the quantitative analysis. To adapt the SPSS software,exclude those less affected variables through backward method,then use the significant test and establish an appropriate model. The result indicates that the infected number is only relative with the GDP and the population of each province,and GDP is inversely proportional to the population of each province(ie,morbidity and GDP is inversely proportional). The tested model is a valid model with predictability.更多还原
