Hi all,
I have a very small complaint to make about the GUI label "Model" in the
main gretl window. I think Model is misnamed since it doesn't contain any
models. The drop down list consists of estimators, right? I make a big
deal about the differences between models and estimators in class, there it
is in gretl contradicting me.
Cheers,
Lee

Well, I'm not sure I'd say that gretl is contradicting you. I guess
the full title of this menu item ought to be "Specify and estimate a
model" but it has to be abbreviated: should the abbreviation indicate
the process (specification + estimation), the tool (estimator) or the
end result (an estimated model)? The proverbial "reasonable people"
may differ on this.

Since it is one of the most active/important/used menu item in gretl, it is
important its name.
Would "Modelization" be a good single name?
Other options:
Model Specification and Estimation
(I think it is OK to have a long name, because gretl is not prepared for
small screens like mobile phones)

IMO "Model" is just fine. Like Allin said, it's shorthand. With the
same logic, the "File" menu should be renamed, too.
And besides, many sub-entries are organised exactly *by model* (eg the
Time Series submenu -- ARIMA, VAR, etc).

You beat me to it! I was just going to suggest that "Estimate" is
about the only acceptable alternative to "Model" that I can think of.
But I think/guess that "Model" is more likely to call up correct
expectations of what's to be found in that menu, for most users.

New subject: A small, pedantic gripe about "models" in gretl: an analogy
What is TSS = RSS+ESS ?
RSS=
1) residual sum of squares
2) regression sum of suares
ESS=
1) explained sum of squares
2) error sum of squares
Some people, e.g. R team, proposed
to solve this enigma using MSS (model sum of squares)
Does all this really important?

Jack's mention of "File" is apt. Allow me to engage in a little more
pedantry here ;-)
In menu headings for English-language computer interfaces a common
trope is to use a singular noun which is also a verb, hence a
bivalent abstraction -- as in "File", and also "Model".
When you see a "File" menu you don't expect it to pull down a list
of files (though a list of recently opened files might be included):
the idea is "Come here for operations relating to files; come here
if you want to file something."
Similarly for "Model": the idea is not that you're going to see a
list of models as such, it's "Come here for operations relating to
models; come here if you want to model something."
If the headings were "Files" or "Models" (plural) the user might
expect to see a list of objects of those respective sorts, but not
if the abstract category is used.
(So I can see where Hélio is coming from with "Modelization" --
seeking the appropriate abstraction. However, the English for
"Modelization" is "Model"!)
In fact, what you see among the first-order elements under the gretl
Model menu is a mixture of names of estimators (OLS), categories of
estimators (Robust), classes of data (Time series), and classes of
model (Simultaneous equations). What all these elements have in
common is that they're to do with econometric modeling.
Allin
6:45 p.m.
Do not see any problems here.
Is "model" a good name? - yes
Is "model" the best name? - do not know,
since nobody showed me the optimality criterion.
I am not sure whether there's demand to develop such
criterion for this situation.
Of course, we shouldn't speck of changes
before having such criterion.
Let it it stay

Paraphrasing Allin's point, basically the word "Operations" implicitly
follows the main menu items: "File Operations," "Data Operations,"
"Model Operations," etc. Personally I'm ok with that remaining implicit.

I can see I'm not getting much love on this one! :) It's ok though.
I'll add a few comments and then surrender.
1. For command line users this is not relevant since those of us who work
that way know that ols is an estimator and that ARIMA is a model that can
be estimated in various ways. These are experienced users who know the
fine distinctions and see the issue as much ado about nothing. However,
GUI users tend to be less 'sophisticated' (ok, I admit that I often use it)
and less likely to know that ols is an estimator and not a model. I have
some evidence since I asked that question (Is least squares a model or an
estimator?) to an introductory graduate class and only half got it right.
2. Econometrics software like Gretl doesn't model, Gretl users model.
Gretl only estimates the parameters of a model known to the user and which
hopefully encompasses the DGP from the collected sample.
Estimators are chosen because of their sampling properties; the sampling
properties depend on the (statistical) model. A model is not chosen
because of the properties of its estimator. In my mind, a model should be
(carefully) chosen before the software is opened (e.g., Hendry's GUM?).
Even in the model pull-down menus, the tree (or dialog box) ends in every
instance at an estimator, e.g. simultaneous equations>sur or tsls or
whatever. Now, I know there may be some of us who do the following: grab
some data, run some regressions, decide upon a model that explains the
results. Write it up as if this were done in reverse order. Can anyone be
surprised that people are skeptical of what our studies find?
3. "Model" can be a very good organizing structure: Panel, Time-series,
Linear, Nonlinear, Simultaneous Equations, etc, but the user is expected to
choose the method by which the parameters of that model are estimated. As
we all know, an estimator can be used to estimate parameters in many
different models, just as a model can have several estimators. If Model is
kept as the top level organizing principle, then I think each of the
options in the first level of the pull-down should be models. All roads
down the tree end at an estimator.
OK. Now I surrender!
FYI, Stata uses "Statistics" as the top level in their very unwieldy and
confusing GUI. Their manuals are organized according to models, with
estimators and statistics within each context specifically documented.
Although Stata's use of 'Statistics' is correct, it is by no means better
than what gretl has now. Gretl separates out things into "sample" that
Stata does not. Gretl is much cleaner.
I'm just cranky because after 8 weeks of talking models and estimators not
being the same thing, half my class decided OLS is a model, not an
estimator. Argh!.
Cheers,
Lee
And of course, I can be completely wrong..... :)

I haven't read all of this thread carefully and I tend to think some
other menus are likely to be even less intuitively descriptive (to me at
least) than "model", but I think there's some truth to what Lee says.
What distinguishes the entries in the model menu from most of the stuff
in the other menus is that it's about relationships between two or more
variables. (Exception: The bottom part of the View menu also has such
things.) So one could call it Relations or Relationships I guess, but
unfortunately those terms are not very widespread in statistics or
econometrics I guess.
In the end it's very hard to find short and adequate summary terms.

It's interesting how different languages
speakers treat "model".
My own language has no articles and I
perceive "model" as "a model".
Of course, "ols" is not a model, but
"ols regression" is.
I think it's better to ask Gretl team rather than
changing menus every time an instructor
meets a stubborn student.
For, example, currently I don't know the logic
behind placing "arima..... --x-12-arima" under "model"
and X-12-ARIMA under "variable".
But, certainly, Gretl team DO know, and, having the time,
could inform me. Then I could pass the answer to "children".

you, Oleg! :-) A regression is a conditional mean E(y|X), which may be
linear or it may not (e.g., probit). OLS is one of several possible
estimators of a linear regression model. The model must also include other
information about the DGP as in how the variables are generated (both y
(unit root?) and x (fixed?, random?, jointly determined?) as well as
properties of what is excluded from the model, errors. Software knows
nothing of this. That is for the user to consider upon prior to choosing an
estimator.
Students aren't being stubborn, its me who is stubborn! And cranky .... !
Cheers,
Lee

It's interesting how different languages
speakers treat "model".
My own language has no articles and I
perceive "model" as "a model".
Of course, "ols" is not a model, but
"ols regression" is.
I think it's better to ask Gretl team rather than
changing menus every time an instructor
meets a stubborn student.
For, example, currently I don't know the logic
behind placing "arima..... --x-12-arima" under "model"
and X-12-ARIMA under "variable".
But, certainly, Gretl team DO know, and, having the time,
could inform me. Then I could pass the answer to "children".

Yeah, maybe it should be called just that, "Modeling". (Not pushing it,
but also not being ironic.)
In any case, as Ignacio and others have implicitly said, this
verb-noun-ambiguity often doesn't work in non-English languages, so we
translators can do what we want anyway, hehe.

Yes, but with how many "l"s? British or American? ;)

We definitely need a team of translators for en_GB, en_US, en_AU etc...

I choose the Bernouli, oops make that Bernoulli, approach. Sometimes using
1 "L" and sometimes "2." There is a parameter in there somewhere that
must
be used in generating pseudo-random uniforms ....
I've resolved the English version "Model" problem by telling people that is
the shortened form of "Models and their Estimators," which is way too long
to put in the GUI. :) I'd suggest a new model icon though, perhaps a gif
of Gisele Bundchen or Derek Zoolander?
