Can you create the dummy variables yourself? Or maybe use xi, e.g.
sysuse auto
xi: mfp: regress mpg weight displacement i.foreign
Having said that, whenever Stata won't do something that I would
expect it to allow, I wonder (1) is there a good statistical reason
for not allowing me to do it, or (2) have they just not gotten around
to programming it yet?
