Hi, once I asked about gets estimation. Now I found something what could be (maybe) usefull. And it could be implemented (maybe) in gretl. This code for gets estimation is already implemented in Grocer (http://dubois.ensae.net/grocer.html) which is open source! Taken from Grocer web page: - a pc-gets like device, that performs automatic general to specific estimations - etc. What do you think? Is it possible?
