One error I see is that when using -margins- you should _not_ use the
-xi- prefix. You can and should still prefix categorical variables
with -i.-.  In essence, -margins- uses information you give it through
the new factor variable notation (see: -help fvvarlist-), so in order
to use -margins- correctly you need to use the factor variable
notation correctly. Using the -xi:- prefix means you are using the
older and obsolete factor variable notation.

Hope this helps,
