Hi Sven, thanks for the time indeed. My purpose of using a one-step GMM is for robustness
test.

I don't understand -- if TSLS does what you want, why do it via GMM? If
it doesn't do what you want, why try to get identical results? Or is
this a way of testing/checking gretl?

Yeah Sven, I hope to get numerically identical results. Beyond this
wish, I also hope to get the Sargan OIR test results( which do not
appear in my GMM approach)

So it does run it seems. What's your aim now? To get numerically
identical results, but why? Or are you worried that the results are
"too" different? (In which case presumably it's not a gretl problem, but
a matter of your application.)
cheers,
sven
