dear all,

is there a possibility in STATA to estimate seemingly unrelated
regression models if there are unequal numbers of observations for the
different equations?
My guess is that you use a different -iweight- variable for each equation, each equal to one for observations/clusters in the sample for that equation and to zero for observations/clusters not in the sample for that equation. (But don't quote me on that.)

Best wishes

Roger
