The problem is conceptual rather than technical. With -xtlogit- you
introduce a group level component that you do not model completely;
either you condition them out (fixed effects) or you represent them
with a distribution of possible values (random effects). However, the
predicted probabilities depend on this incompletely modelled
component, so that is a problem for a prediction table.
