【摘要】：多元统计方法是基于数学统计方法对多变量的问题进行研究,这些变量通常被称为指标,通常,指标反映的是评估对象的信息,这些信息可能会出现重叠的现象,一定程度上指标与指标之间还有关联,即相关性。为了更好的选取变量指标,使得它们所反映的评价对象之间不出现重叠,多元统计方法是一个适用的分析方法,它可以更加全面、系统地分析和解决问题。多元统计方法包括聚类分析方法、主成分分析法、因子分析法、判别分析法等,它已经被成功应用于评估城市竞争力、评价居民消费水平能力、预测国民经济走势、自然学科建设、中西医治疗效果等领域,解决了大量的实际问题。本文介绍了多元统计分析方法中的聚类分析法、主成分分析法的相关理论及它们在生活中的应用。首先分别介绍了这两种多元统计方法的理论,在介绍了它们在湖北省部分地区孕产妇体质中的应用。以湖北省部分地区的孕产妇为研究对象,通过聚类分析法,找出了几种不同类型的中医体质,通过主成分分析法,找出了影响妇幼卫生健康评价的三个主成分因素。然后综合多元统计方法和数理统计方法,以上述地区的孕产妇为研究对象,通过对孕妇孕早期体质指数BMI和孕期体质指数增加值△BMI进行分析,得出了它们对妊娠结局的影响。最后针对上述研究结果,提出了一些建议。
[Abstract]:Multivariate statistical methods are based on mathematical statistics to study multivariate problems, which are often referred to as indicators, and indicators usually reflect the information of the evaluation object, which may overlap. To a certain extent, there is a correlation between indicators and indicators, that is, correlation. In order to select the variable indexes better, so that there is no overlap between the evaluation objects reflected by them, the multivariate statistical method is a suitable analysis method, which can analyze and solve the problems more comprehensively and systematically. Multivariate statistical methods include cluster analysis, principal component analysis, factor analysis, discriminant analysis, etc. They have been successfully used to evaluate the competitiveness of cities, evaluate the ability of residents to consume, and predict the trend of the national economy. The construction of natural science and the therapeutic effect of traditional Chinese and western medicine have solved a large number of practical problems. In this paper, cluster analysis, principal component analysis and their application in daily life are introduced. Firstly, the theories of these two multivariate statistical methods are introduced, and their applications in some areas of Hubei Province are introduced. Taking the pregnant and lying-in women in some areas of Hubei province as the research object, several different types of TCM physique were found by cluster analysis, and the three principal components influencing the health evaluation of maternal and child health were found out by principal component analysis. Then, by synthesizing the multivariate statistical method and mathematical statistical method, taking the pregnant women in the above-mentioned areas as the research object, through the analysis of the pregnant women's early pregnancy body mass index (BMI) and the pregnancy body mass index added value (BMI), the influence of them on the pregnancy outcome was obtained. Finally, some suggestions are put forward in view of the above research results.
