Leah K. Nelson <lknelson@ucsd.edu>: You can switch to -areg- which allows pweights that vary within village, and produces identical results to using -regress- and including a dummy for each village (but one). How many villages are there? You may want to cluster at the village level: areg y x [pw=weight_household], a(village) cl(village) On Mon, Mar 9, 2009 at 4:22 PM, Leah K.
