(1991) carried out a principal-axis factor analysis with varimax rotation (N=455 undergraduates) of the item intercorrelations for the 44-item STAXI, providing support for the purported factor structure of the measure. Likewise, Forgays, Forgays, and Spielberger (1997) as well as Forgays, ...
rotation of axessimple structureoblique rotationPromax rotationOrthoblique rotation is a two-stage procedure for obtaining oblique rotations used to transform vectors associated with principal component analysis or factor analysis to simple structure . The first stage will usually be an orthogonal rotation ...

The purpose Of this simulation study is to compare the ability of two commonly used methods of rotation, Varimax and Promax, in terms of their ability to correctly link items to factors and to identify the presence of simple structure. Results suggest that the two approaches ore equally able ...

A method of estimating the asymptotic covariance matrix for unrotated and rotated loadings and rotation matrices in factor analysis is presented. The covariance structure for common factors is expressed by the asymmetric formulation which contains unrotated and rotated loadings, and a rotation matrix...
