You wish to display the odds. One possible solution uses -tabodds-.

Unfortunately -tabodds- does not allow the -by- constrcution, but you could knit
your own using -levelsof-.  For example:

sysuse auto, clear
levelsof rep78, local(levs)
foreach x of local levs {
display _new as text "rep78 = `x'"
tabodds foreign if rep78==`x'
}

If you didn't want the entire output of -tabodds- then you could extract the
r(odds) scalar from the -return list- and just display that.
