You can use the Rotation tab to transform the factors by orthogonal or oblique rotations. (See FigureĀ 27.5.) Orthogonal rotations rigidly rotate the factors; oblique transformations introduce correlations between the factors. Transformed factors are often more interpretable in terms of the original variables.
The Rotation tab contains the following UI controls:
specifies the rotation method. You can select from a set of common orthogonal or oblique transformations. This corresponds
to the ROTATE= option in the PROC FACTOR statement.
specifies the power of the square roots of the eigenvalues used to rescale the eigenvectors for Harris-Kaiser orthoblique
transformation. This corresponds to the HKPOWER= option in the PROC FACTOR statement.
specifies the power for forming the target Procrustean matrix. This corresponds to the POWER= option in the PROC FACTOR statement.
specifies the method for normalizing the rows of the factor pattern for rotation. This corresponds to the NORM= option in
the PROC FACTOR statement.
