This question is not well-formed. It's very important to specify what
procedure you are using and what you mean. If it's the -fraclogit-
procedure that can be downloaded (-findit fraclogit-) the answer is
that you specify the interactions in the usual way (i.e., with # and
## between terms you want to interact) and can get a Wald test via
-testparm- in the usual way. -lrtest- does not appear to work directly
because this is a quasi-likelihood model and the log-likelihood term
is not saved.
