Subject: Re: factor analysis of nominal data

Steve Runfeldt-2
Have you looked at Multidimensional Scaling [Scale/ALSCAl]?  This is should
do what you are looking for.
It is in the SPSS Base in v16.

By the way, with such a small population you are conducting a census not a
sample, so much of the rationale behind probability sampling goes out the
window.  The results are what they are.

Regards,

Steve

Will have to buy the categories module in the future, I guess.

Concerning the limited no of cases : I shall get some more cases in the
near future but the upper limit will be 68 as this is the universe. So I
don't work with an sample but with the complete population. Numerous
variables and few cases is the standard in organisational analysis. Now
what can you do if you are limited in this way?
