You would want to check whether anything meaningful at all is returned
by your command. At the face value, it looks OK, but who knows how it
would interact with your data.
It looks like you are doing some sort of difference in predictions
work that -margins- can be used for. You would need to run your model
with full interaction with -rhc- variable, whatever it is, and then
figure out what exactly out of 111 specifications that -margins-
support is the one that you need. No need for bootstrap, there's a
need to RTFM :))
