gretl crashed while searching for file within GUI
by Fred Engst
Hi Allin,
gretl crashed once again, but for a different reason this time.
It seems that whenever I tried to do a search for files within GUI after “file->Open data->User file...” or “file->Session files->Open session…”, it crashes right after it showed a list of files.
I can’t remember a time when I did a search like this without gretl crashing.
I suspect it has something to do with my character encoding. Even though I use standard English, I have Chinese on my system also.
This is more like a FYI, and it is not urgent, as I know how to get around it easily.
Attached is the crash report if it helps.

Wish-list: How about having robust standard error as the default on the GUI check box, etc.
by Fred Engst
Thanks Allin.
It was my mistake of not recognizing the coeffsum is a restriction with only 1 d.o.f.
While we are on the topic of wish-list,
1. Why can’t we make the robust standard error as the default on the GUI check box?
Is there any situation in which a robust standard error will be biased and wrong?
By having the default being robust, those that insist on having the homoskedastic standard errors reported can uncheck the check box.
2. Is there any reason not to have time dummies included as the default in a panel data regression? Those that have variables that only change with time should uncheck the include time dummy check box.

Wish-list: Ordinary least squares as formula when there are more than 5 variables
by Fred Engst
Hello to all the hard working team members who have work on building this beloved gretl.
I have another item on the wish-list.
I found that Ordinary least squares as formula only works when I have no more than 5 variables. Otherwise, the file commend item is dimmed.
Would it be hard to make gretl to formulate multiple lines of the formula?
I can try to write a script to do just that. Do I have to, or should I give it a try?
Thanks,
Fred

Ordinary least squares as formula
by Philippe
Hello,
I'm new to gretl and i was wondering if it's possible to get the ordinary
least squares as a formula. I mean without having to copy the coefficients
and having to assemble a formula myself. I couldn't find such options. Does
anyone know a solution for that?

Any way to make coeffsum quiet?
by Fred Engst
Thanks Allin so much for such a quick response and fix to the crash report.
Relating to the coeffsum and restrict command block, however, I have a few questions.
1. In my script, I need to make the coeffsum be quiet, but that seems not to be an option. Would it be hard to add one?
2. Coeffsum gives a t-test reading while the restrict gives an F-test result. I prefer the t-test result for it gives me the sign of the sum, but shouldn’t both be an F-test?
Thanks,
Fred

Package MCO_Ridge.gfn to be retired soon
by Sven Schreiber
Dear all,
this is again an announcement about contributed function package
reorganization: The package MCO_Ridge.gfn by Uriel Rodríguez Ramírez is
going to be retired soon due to certain technical issues. Uriel couldn't
be reached anymore to update the package.
If you are an active user of the package you would have to keep a local
copy for yourself. Alternatively you could use the package ridge.gfn
which has been available since 2017 and which also performs Ridge
regression, as the name suggests.
(Disclaimer: I am the author of ridge.gfn, but this has nothing to do
with the removal of MCO_Ridge as the two packages have lived happily in
coexistence so far. Obviously this is open source software and I don't
get any profit from it.)
cheers

gretl crashed with a message of "Abort trap: 6 "
by Fred Engst
My beloved gretl crashed on me. (:
My scrip was doing great for that last year until I added a line with the coeffsum command.
It repeatedly crashed over and over again.
So I setup a small test dataset and invoked gretlcli, and it seems that coeffsum worked the first time, and crashed the 2nd time with an error message of "Abort trap: 6”.
What did I do wrong?
Here are the files that you might need to replicate the situation and help me out:
1. a test dataset,
2. the scrip that crashes gretlcli
3. the log from gretlcli
4. two crash reports when I did run gretl & gretlcli.

Maximum likelihood
by Olasehinde Timmy
Dear professors
Please, I would like to know how to use a matrix function in maximum
likelihood estimation of the below specifications ( asterik variables are
function of parameters)
series e1 = y - y*
series e2 = x - x*
series v1 = var(e1)
series v2 = var(e2)
series v12 = cov(e1,e2)
matrix U = {e1;e2}
matrix V = {v1,v12;v12,v2}
mle ll = -N/2*log(2π) - 1/2*log|V| - 1/2*U'*inv(V)*U
Is the above specifications possible? Please kindly help.

Orthonormal matrix
by Olasehinde Timmy
Dear Professors,
I am having an issue in computing the orthonormals of alpha and beta in the
Beveridge Nelson decomposition of cointegrated VAR model. For example, the
F matrix that describes the permanent components. For illustrative purposes
using vecm output, let α = {-0.3;0.4}, and β = {1,2.2}, how can I compute
the orthonormals for this two matrices. Because, I tried using the
nullspace command in gretl, but I keep getting empty space matrix.
Thanks.
