Hello,
The manual specifies Promax as a rotation method for the factor
analysis. I cannot call up this method via the menu. If I enter it via
the syntax, a factor analysis can be run - but in my dataset:
1) the sum of squared loadings is not calculated,
2) instead of a rotated matrix I get a "pattern matrix (Mustermatrix)".
Maybe it's the same?
With Varimax there is no problem.
What have I overlooked?
Thank you.
Kind regards
Andreas Hammer
