st: Applying DESMAT to Log-linear saturated models

Dear Listers,

I have a somewhat technical question.

At the UCLA Stata FAQ site, it can be read that Hendrickx's 
DESMAT be used to generate a saturated model for
Agresti's afterlife data.


However, isn't this inappropriate when fitting a saturated model
for a contingency table? Using DESMAT POISSON would indicate
that count is the dependent variable with error terms poisson distributed.

In addition to that, the output shows "model degrees of freedom=11", 
the saturated model has 0 df by definition as it fits the data perfectly.

Maybe I am so wrong or stupid or both that I don't get it, but I'd really
appreciate your comments.
