Hello there
I'm dealing with a simulatenous equation system like the following
one and I'm using ivreg to calculate the parameters
ivreg y1 x1 (q1 q2 q3 =a b c)
ivreg y2 x1 (z1 z2 z3 =a b c)
ivreg y3 x1 (q1 q2 q3= a b c)
I want to impose certain symmetry, for example, parameter of
q1=parameter of z1 and parameter of z2= parameter of q2. I have
tried to use the constraint option but I get a massage that
constraint option is not allowed for ivreg. Any suggestions woulde
be apprecciated!
Thanks in advance!!
Andres
