The typical trick for that is to estimated them all in one model and
add interactions of your group identifier with all your explanatory
variables. You can use -constraint-s to remove some explanatory
variables from some of your samples, i.e. set the effect of those
variables in those samples equal to 0.
Hope this helps,
