【摘要】： 本文利用判别分析理论与方法对中南大学湘雅二医院肝硬化患者医疗数据进行了数学建模与数据处理,得到了一些有实际意义的结果,主要工作包括： (1)介绍了统计学的起源、发展以及在我国的发展情况及现状,然后介绍了多元统计分析的相关概念以及逐步Bayes判别分析理论； (2)收集中南大学湘雅二医院肝硬化患者的医疗诊断数据和治愈情况数据,从中挑选出指标比较齐全的样本； (3)利用判别分析的基本思想和方法,建立了逐步Bayes判别函数模型,然后根据所建立的逐步Bayes判别分析模型确定算法,再用Spss统计软件对模型进行求解,得出了比较有用的能判别样本归类的判别函数,最后对所得到的结果进行了分析。在本文的研究中,根据分析过程和医疗数据处理的结果,我们的主要结论包括： (1)得到了三个有意义的能判别样本归类的函数判别式； (2)把患者入院时的医疗指标最大值代入判别函数,能区分以后患者的治愈情况,并且这种准确性达到80%以上；(3)推广了逐步Bayes判别分析的应用范围,并对未来进一步的研究方向进行了展望。
[Abstract]:In this paper, the medical data of patients with liver cirrhosis in Xiangya second Hospital of Central South University are modeled and processed by discriminant analysis theory and method, and some meaningful results are obtained. The main work includes:This paper introduces the origin and development of statistics and its development and present situation in China, and then introduces the related concepts of multivariate statistical analysis and the theory of stepwise Bayes discriminant analysis.(2) collect the medical diagnosis data and cure data of cirrhosis patients in Xiangya second Hospital of Central South University, and select the samples with complete indexes.3) based on the basic idea and method of discriminant analysis, a stepwise Bayes discriminant function model is established, and then the algorithm is determined according to the established stepwise Bayes discriminant analysis model, and then the model is solved by Spss statistical software.A useful discriminant function for discriminating the classification of samples is obtained. Finally, the results obtained are analyzed.In this study, based on the results of the analysis process and medical data processing, our main conclusions include:1) three meaningful discriminant functions are obtained to distinguish the classification of samples.(2) adding the maximum value of medical index to the discriminant function on admission can distinguish the cure condition of the patient in the future, and the accuracy is more than 80%. The range of application of stepwise Bayes discriminant analysis has been extended.The future research direction is prospected.
