Hi Hector

The answer you gave Kaat is also very helpful for me. I have 2 additional questions:

1. Do you have any literature at hand I could cite concerning the fact that for authentic binary variables classical factor analysis (not CATPCA) should be used?

2. I performed a factor analysis and a CATPCA with the same data (13 binary variables, 3 components) using SPSS 23. The resulting component loadings are practically the same with classical factor analysis as with CATPCA, but with CATPCA (not with classical factor analysis) the varimax-rotation fails (error message "Rotation failed to converge in 5 iterations. (Convergence = .000)."). Do you have an explanation for this difference?

Thank you!
Mirjam
