引言因子分析是一种多元统计分析方法,是化学计量学的一个重要分支。在因子分析中,通过把一数据矩阵分解为两个数据阵(一个行阵和一个列阵),找出影响数据矩阵的因子个数以及各因子对数据的影响程度。随着计算机的广泛应用,越来越多的化学工作者借助因子分析这一有力工具解决复杂的多变量问题。近年来,国内外对因子分析这一领域的研究十分活跃,并有专著 Introduction Factor analysis is a multivariate statistical analysis method that is an important branch of chemometrics. In Factor Analysis, a data matrix is ​​decomposed into two data matrices (one row and one array) to find out the number of factors that affect the data matrix and how each factor affects the data. With the widespread use of computers, more and more chemists rely on the powerful tools of factor analysis to solve complex multivariable problems. In recent years, the research on factor analysis in this field both at home and abroad has been very active and there are monographs
