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.
(see http://www.ats.ucla.edu/stat/stata/faq/desmat_saturated_Model.htm)
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",
however
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.
Best regards,
Marcus
