In this paper we compare and contrast the objectives of principal component analysis and exploratory factor analysis. This is done through consideration of nine examples. Basic theory is presented in appendices. As well as covering the standard material, we also describe a number of recent developments. As an alternative to factor analysis, it is pointed out that in some cases it may be useful to rotate certain principal components if and when that is appropriate.
在本文中，我们比较并对比了主成分分析和探索性因子分析的目标。这是通过九个例子的考量来完成的。基础理论在附录中给出。除了涵盖标准内容外，我们还描述了一些近期的进展。作为因子分析的一种替代方法，文中指出在某些情况下，如果合适的话，对某些主成分进行旋转可能会有用。
