Can somebody tell me how to interpret the output of CATPCA in SPSS and how to obtain the scree plot?
Thanx. :) |

Please be a little more specific? This is not the place to regurgitate the FM.

Perhaps this is a good time to remind people
of the Case Studies available from the Statistics Help menu. In particular,
the Categories option case studies include a discussion of how to use CATPCA
and how to interpret the output.

(Excuse the snark)
Perhaps this is a good time to remind people that there are entire books written on the subject and that Google is your good friend! --

I want to know how to adjust the following warning I get when I do the CATPCA more than for 2 dimensions.
This warning says how to obtain the scatter plot of pairs instead of matrix plot. But I couldn't understand how and where to use the key word 'NDIM'.. Thanx in advance :) "To obtain scatterplots of pairs of dimensions in stead of a matrix scatterplot you can use the NDIM keyword with the PLOT subcommand: NDIM(d1,d2) produces scatterplots of dimension d1 plotted against all higher dimensions up to d2." |

In your syntax window place the cursor on "catpca" click the
<f1> key. <f1> is <Help>
and may in fact have that written on the key.
If you forgot to exit the menus via the <paste> key, you need to go back to the menus, and now exit via the <paste> key. That will show the syntax (i.e., commands you are giving the computer) in a syntax window. then you can place you cursor and click <help> on the keyboard.
