I might be sorry for asking this question :-)
I have two equations and I tried to estimate them individually with "lm"
and "gls", and then in a system (using systemfit) with "OLS", "WLS" and "SUR".
Quite surprisingly (for myself at least) the results are identical to the last
digit.
Could someone (please!) give a hint as to what am I doing wrong?
Thanks,
mihai
