Abstract
Varimax and oblimin trasformations of significant principal components of complete intercorelation matrixes and significant principal axes of image matrixes of covariances were compared.
Varimax poorl approximates simple structure, tending to produce general and poorly defined group factors and sometimes integrating those factors which in oblimin position are highly intercorrelated.
Oblimin ususally gives very simple structure with well defined factors, especially if significant principal axes of image matrixes of covariances are transformed.
The same analyses using the same tests on 9 subsamples (of which some overlapping from the same population were very similar. Not only that varimax invariance was not higher than direction oblimin invariance, but it was, as a rule, significantly lower.
Therefore, ti seems that oblimin transformation of significant iage axes is very suitable method for explorative factor analyses of psychological measurement instruments.
