Dear. All

I am struggling how to get the coefficient from the SUR or system estimation.

I know that, In case of simple regression, If I want to get the coefficient to recycle it,

Y cosnt X1 X2
after the regression, we could get the coefficient from following command

genr aaa = $coeff(X1)
genr aaa =$coeff(const)

However, I could not find how to get the coefficients from SUR or System estimation

for example, in the following SUR estimation
================================================
system name="Rotterdam"
equation wdq1 DivisiaQ ddp1 ddp2 ddp3
equation wdq2 DivisiaQ ddp1 ddp2 ddp3
equation wdq3 DivisiaQ ddp1 ddp2 ddp3
end system

restrict "Rotterdam"
b[1,3]-b[2,2]=0
b[1,4]-b[3,2]=0
b[2,4]-b[3,3]=0
end restrict

estimate "Rotterdam" method=sur --iterate
estimate "Rotterdam" method=3sls --iterate
===================================================

Any suggestions?

Sincerely

Sung Jin Lim
