PRINCALS

PRINCALS is available in SPSS® Statistics Professional Edition or the Categories option.

PRINCALS (principal components analysis by means of alternating least squares) analyzes a set of variables for major dimensions of variation. The variables can be of mixed optimal scaling levels, and the relationships among observed variables are not assumed to be linear.
