Abstract

This article seeks to show that, although factor analysis (mostly in its exploratory version) is a method frequently applied by social-science researchers (it is often also discussed in basic data analysis textbooks), only a very basic version of it is used, with settings that are far from optimal. However, what settings are used can have major implications, primarily in the form of conceptual problems, where the exploratory version is often used instead of the confirmatory version. Other settings used can also have an impact on the results. These are mainly partial options, which are used mainly in the exploratory version, in particular the choice of the correct correlation coefficients, the choice of method for the initial extraction of factors, the choice of the rotation method and the choice of the number of factors with which we want to work in the exploratory version. The text discusses the algorithms for ordinal variables, and the possibility of determining the number of factors through parallel analysis or MAP. The practical example discusses the advantages of the oblique rotation of factors. The article seeks to highlight good practices that best reflect the current state of the art of quantitative methodology and statistics. In addition to the general guidelines, the article contains practical advice about software and recommends a procedural schema for using factor analysis.
本文试图表明,虽然因子分析(主要是探索性的)是社会科学研究人员经常使用的一种方法(它也经常在基础数据分析教科书中讨论),但它只使用了一个非常基本的版本,其设置远非最佳。然而,所使用的设置可能具有主要的含义,主要以概念问题的形式,其中经常使用探索性版本而不是确认版本。使用的其他设置也会对结果产生影响。这些主要是部分选项,主要在探索性版本中使用,特别是正确相关系数的选择,因子初始提取方法的选择,旋转方法的选择以及我们想要在探索性版本中工作的因子数量的选择。本文讨论了排序变量的算法,以及通过并行分析或MAP确定因子数量的可能性。通过实例讨论了因子斜转的优点。本文旨在强调最能反映定量方法和统计技术现状的良好做法。除了一般的指导方针之外,本文还包含了关于软件的实用建议,并推荐了使用因子分析的过程模式。
