Betreff: st: xtreg using only individuals whose DV changes

I am running: xtreg life_satisfaction income married..., fe i(personid)

I would like to run the same regression using only data from those
individuals whose life_satisfaction changes over time.  Is there a way
to do this using the xtreg command?  Or do I need to temporarily drop
individuals whose DV doesn't change -- and if so, how?

Thanks for your help,
