摘 要:随着科学技术的飞速发展,统计学也在不断完善,回归分析的性质和理论也在各个领域内被广泛应用,近年来有许多学者倾向于研究其在医学领域的应用.而本文主要介绍的是主成分回归的稳健性及在医学上的应用,首先我们需要建立一个主成分回归模型,而在建立模型前,还需要了解一下一般回归模型的构造以及主成分回归,而主成分回归则是在主成分的基本思想和性质上提取出来的,因此本文对主成分思想也有一定的介绍.其次,对于稳健性分析,我们不仅要知道主成分的估计量,并且需要用估计量去推出稳健性统计量,这样的话就基本完成了主成分回归的稳健性.而对于它在医学上的应用,我们还需要用主成分回归和主成分分析的方法用统计软件通过实例来解决医学数据中经常出现的多重共线性和异常点的存在.40373 毕业论文关键词:回归模型;主成分回归;稳健性
Robustness of Principal Component Regression and Its
Application in Medicine
Abstract:this paper mainly introduces the robustness of principal component regression and application in medicine, first of all we need to establish a principal component regression model, but in front of the model, also need to know about the general regression model of the structure and principal component regression, principal component regression is the main component of the basic ideas and extracted in nature, so in this paper, the principal component thought also has the certain introduction.Secondly, for robustness analysis, we should not only know the principal component estimator, and need to use the estimator to launch robustness statistics, so it was basically completed the robustness of principal component regression.For its application in medicine, and we also need with outliers diagnosis method by an example to solve the medical data often appeared in the existence of multicollinearity and abnormal points.
