Dear all,
Further to my posting of yesterday "simultaneous equation tobit - can it be
estimated in Stata?", I feel my system is probably more like Seemingly
Unrelated Regression (SUR) than a simultaneous equation system, since none
of the 3 dependent variables (share of distance travelled by car, by public
transport and on foot) appears as an independent variable in the other 2
equations, and yet the independent variables in all three equations are the
same.
Is there a way of estimating a set of three tobit equations as a SUR in Stata?
Thank you once again for your help,
Mark
