Factor analysis error message

Teri Wilson
I am conducting a factor analysis, specifically via principal axis
factoring (PAF) with a Varimax rotation (all all other types of rotations
result in this error message) and under the "Factor Matrix" is the
message "Attempted to extract 4 factors. More than 25 iterations required.
(Convergence=.014). Extraction was terminated."  However, for the "Rotated
Factor Matrix", there is no error message and that the "Rotation converged
in 5 iterations."

When I conduct a principal components analysis, I do not receive any error
messages for any of the matrices - unrotated or rotated.

Does anyone know what this error message means and how I can resolve this?

Thanks so much!

Hello Teri,

There is a default limit of iterations  in FA.

Please try to set a higher number in Menu/Analyse/Data reduction/Factor/Extraction/Maximum iterations for convergence.
