Description

In exploratory factor analyses (EFA), factor rotation techniques are needed to interpret the result of EFA, and thus, many factor rotation methods have been developed. This paper overviews the factor rotation problem and rotation methods for the problem. Although factor rotation problem is very traditional one, there are some recent works including a rotation method using component loss functions, which has been investigated theoretically. Various factor rotation criteria are introduced and optimization algorithms for the criteria are explained. Furthermore, the use of rotation techniques in structural equation modeling and regularized approach are described.
