| 摘 要： | Orthogonal rotations,e.g,the varimax rotation,are common practice in factor analysis.However,theterm varimax rotation does not refer to a unique procedure,since several different types of rotation arepossible.In this paper six different types of rotation are examined(raw varimax of loadings,normalvarimax of loadings,raw and normal varimax of scores,eigenvalue-weighted varimax of loadings andArthur varimax)from both a theoretical and practical point of view.It can be concluded that an adequateapplication of these methods can often simplify the interpretation of the calculated factors.
