I know that
it was a pseudo-syntax. Nevertheless, in order to fill in the gaps in it, I need to figure out how does the syntax you propose work. Indeed, I do not understand very well the loop... how can I narrow the cluster analysis (in the second stage) to each group created at the first stage? 


Thanks,
Matt
