Exploratory factor analysis is often confused with principal component analysis (PCA), a similar
statistical procedure. However, there are significant differences between the two: EFA and PCA
will provide somewhat different results when applied to the same data.
• The purpose of PCA is to derive a relatively small number of components that can account for the
variability found in a relatively large number of measures. This procedure, called data reduction, is
typically performed when a researcher does not want to include all of the original measures in analyses
but still wants to work with the information that they contain.
• Differences between EFA and PCA arise from the fact that the two are based on different models. An
illustration of the PCA model is provided in figure 2.1. The first difference is that the direction of
influence is reversed: EFA assumes that the measured responses are based on the underlying factors
while in PCA the principal components are based on the measured responses. The second difference is
that EFA assumes that the variance in the measured variables can be decomposed into that accounted
for by common factors and that accounted for by unique factors. The principal components are
defined simply as linear combinations of the measurements, and so will contain both common and
unique variance.
• In summary, you should use EFA when you are interested in making statements about the factors that
are responsible for a set of observed responses, and you should use PCA when you are simply interested
in performing data reduction.
当你关注的是对一组观测响应的对应的因子做出解释时，可运用探索性因子分析
这句话可以换个别句子吗，感觉好拗口
• 主成分分析的目的是导出可以表示测量中的相对大的数的变动性的成分的一个相对小的数。这一分析过程称为数据约简，当一个研究者在分析中不愿采用所有原始测量数据但又希望运用其所包含的信息时通常开展的一项工作。
• 探索性因子分析与主成分分析的差异来源于这两个方法基于不同的模型这一事实。主成分分析模型的描述如图2.1所示。第一个差异是两者的影响方向相反：探索性因子分析假定被测响应是基于内在因子，而主成分分析假定主成分是基于被测响应。第二个差异是，探索性因子分析假定被测变量的方差可以分解为用平常因子表示的部分和用非平常因子表示的部分。主成分被简单地定义为测量值的线性组合，这样就可同时包含平常因子方差和非平常因子方差。
• 总之，当你关注的是对一组观测响应的对应的因子做出解释时，可运用探索性因子分析；如果你仅仅是对做数据约简感兴趣，就可运用主成分分析。追问
the measured responses是专业术语吗，被测响应是数学里的名词吗
追答measured responses是数学、机械、自动化中的术语，又可译为“实测响应”，是通过采样得到的现场数据。
