Re Factor Analysis discussion

[Katina Dimoulias]

Hi,

Just to follow on from Hector's suggestion to use Categorical Principal
Component Analysis for categorical and ordinal data - could you please let
me know exactly how to find that in SPSS.  I have been using Principal
Components for my factor analysis with categorical and ordinal variables,
is this the same as the above?

Thanks,

Katina

Hi Katina,

No, it's a separate procedure. If you have the Categories add-on module,
then it will be under Analyse > Data Reduction > Optimal Scaling. Or,
via syntax it's the CATPCA command.

Cheers,
Kylie.

         Ordinary Factor Analysis, operated by command FACTOR in the Base
module, performs Principal Component analysis as one of its options, but it
assumes all variables are interval scales. Command CATCPA is in the optional
Categories module, and stands for Categorical Principal Components Analysis.
