Could someone be so kind and comment on the connection between beta
coefficient in multiple regression and the effect size. I am familiar
with using Rsq as an estimate of the effect size but I think it relates
to the effect size of the overall model. But if I want to estimate the
effect size of one particular predictor, I should use the beta, right?
But how does beta translate into the effect size? Thanks for your help
and patience in advance :)

Jon is right (but MCA was introduced in 13). Some more clarification:
HOMALS performs  MULTIPLE CORRESPONDENCE, the algorithm is the same in
both procedures; MCA offers more analysis options and more output than
HOMALS.

A little clarification: HOMALS has been superseded by MULTIPLE
CORRESPONDENCE in newer versions of SPSS (introduced in 14, if memory
serves), and the Optimal Scaling menu will take you to that procedure
now, although HOMALS is still in the system.

In the menus, specify

Data Reduction -> Optimal Scaling

and work with All Variables Multiple Nominal
and One Set of variables.

This specifies HOMALS, also called
homogeneity analysis or multiple correspondence analysis.
