Re: [Gretl-users] New mailing list?

Dear all, I think this is a very relevant discussion, so let me share some thoughts. I agree with Jack that setting up a general discussion of econometrics could end in a "do-my-homework-for-myself" thing. I'm not an econometrician, just an amateur user of econometrics. As such, hundred of times I was in desperate need of quick answers for econometric issues of mixed origins. My problem is I do not understand Gretl or Econometrics? My problem is that I have not read the Gretl manual enough? I have tried to avoid specific econometric discussions in Gretl list, because I think everyone has been polite and patient, I should not gone too far using others people time. I think Google could be a much better research find place than the proposed list, although some people have generously share their knowledge on a lot of issues. I think there are two roads that maybe should be explored, and I am trying to sum up some of the emails that others send upon this topic. Please, do not feel the following reflections as critics, nor demanding more work to those that gently spend their time to simplify our work. I expect them to be path for improving Gretl. My reflections will be targeted upon the use of the Gretl console or the construction of inp files. 1) The Gretl documentation some times is obscure on the specific way that one should proceed in order to do things work. This came in two ways. First, sometimes the commands itself have sometimes a narrow explanation. Some have examples and others not, and as in Murphy's Laws the day you lack examples when you need some specific command. As an example, I found that Gretl documentation is scarce on how commands work in panels. But not how to do econometric, but how to manipulate and how work specific commands in panels. Second, in the Gretl Guide, which I think is also a good reference econometric text, some inp examples are good for the topic at hand (and work!), but some lines need more explanation. I regret not having a good example right now, and this weaken my argument. This also happen when they are references to C++ commands. 2) The Gretl User guide abounds in econometric explanations (how to decide between random and fixed effects) which is excelent! But it lack explanation on the specific way it is calculated. As an example, in the command meantest --unequal-vars I was asked on which is the specific formula used. I have no answer but "in the usual way, I think". In panels I have another answer from a colleague on the specific way Gretl estimate the parameters (which I do not remember now, sorry) and I could not find the answer. The first point could be easily handled, and those who do not program could make some suggestions. The second one I think could require more work in order to translate the code to a readable text. I think this two lines of work could improve Gretl and also spread its use. When I talk to people which use STATA in order to convince them that Gretl is not less than STATA, I found a barrier in the details of the specific calculations (among some spread fear that associate free with not god as payed).
