The essential idea in all analytical rotation schemes for approximating Thurstone's simple structure is to split the factor loadings into two groups, the elements of the one tending toward zero, and of the other, toward unity. In the PROMAX method, the loadings of a preliminary factor pattern are raised to a fixed power to provide a target for Procrustean rotation. In this article, a mathematically better-motivated technique based on vector majorization is proposed for this purpose. The method is illustrated with several standard numerical examples.
所有用于逼近瑟斯顿简单结构的解析旋转方案的基本思想是将因子载荷分为两组，一组元素趋于零，另一组趋于一。在PROMAX方法中，将初步因子模式的载荷提升到一个固定幂次，以提供普罗克汝斯忒斯旋转的目标。本文为此提出了一种基于向量优化的数学动机更强的技术。用几个标准数值例子说明了该方法。
