Dear Profs (Particually, Allin & Sven).
I hope my email finds you well. I noticed that Gretl doesn't incorporate performing non-linear restriction tests on the estimate. Is there something I am missing? If yes, please let me know. However, I would suggest that the lords of this good software help those who don't understand coding by incorporating this test just like the other packages into the next release of Gretl.
Hi,
the contributed package "waldTest" by Oleh Komashko does that. Please check it out and tell us if it works for you.
cheers
