I have a questions on Simultaneous Equations Model implementing using SAS,
x = f(y, z1, z2)
y = f(x, z1, z3)
I tried to use 2SLS in proc model to estimate, however it seems that SAS implement them separately and get two R^2 for each model, is that a way to estimate simultaneously and get a system-wide R^2?
Hope anyone can provide me the answer, I really appreciate that.
