Promax rotation spss

WebFeb 9, 2024 · Version 16 of SPSS offers five rotation methods: varimax, direct oblimin, quartimax, equamax, and promax, in that order. Three of those are orthogonal (varimax, quartimax, & equimax), and two are oblique (direct oblimin & promax). WebPromax rotation begins with Varimax (orthgonal) rotation, and uses Kappa to raise the power of the loadings. Promax really reduces the small loadings. Promax also runs faster …

WebJun 7, 2024 · Promax is a fast and efficient method for oblique factor rotation. In this procedure, a varimax rotation (usually preceded by Kaiser normalization; Kaiser, 1958) is performed first to obtain an orthogonal solution, which is then transformed into an oblique solution (Hendrickson & White, 1964 ).

http://core.ecu.edu/psyc/wuenschk/MV/FA/FA-SPSS.pdf WebPromax Rotation Reduces Cross-Loadings A problem with this solution, though, is that many items load on 2 or more factors simultaneously. Such secondary loadings are known as cross-loadings and conflict with the basic factor model as shown below. Each item measures only one trait and should thus load substantially on only one factor.

WebNov 27, 2014 · If, as you say, there's no difference between SPSS and R results under no rotation or varimax rotation, then, logically, the cause of the difference you had observed is due to some difference in the promax rotation.
