Actually I don't expect that the vintage of the snapshot makes a
difference in this case (although you never know...).
Could you try with a public/example dataset that comes with gretl and be
very precise which restrictions you are trying? Perhaps even a small
screenshot. Maybe you're trying something that leaves one subsample
empty, or similar.

Hi Peter, it works for me here with the latest snapshot, actually it's
the first time I have done this. Did you put the restriction in
parentheses as described? Did you hit enter while the variable selection
box had the focus? I think this is also necessary.
So thanks for the reminder about the help text there - I would never
have guessed from the interface that something like that was possible.
I'm wondering whether perhaps the restriction formulation should get its
own optional field to make it clearer.

bug in test stat calculator
by Summers, Peter
Hi all,
I'm trying to follow the sub-sample restriction example in the help menu for the test statistic calculator for comparing 2 means. I select the same variable in both slots and specify the restrictions, but when I hit the enter key the mean, std. dev. & sample size boxes get cleared out. Am I missing something? This is on Widows, gretl 2024c-git.
Thanks,
Peter

contrib. package Box_Cox_Value to be retired
by Sven Schreiber
Dear all (again),
this message is indirectly related to yesterday's announcement about an
update of the BoxCoxFuncForm package: the similarly named package
Box_Cox_Value by Pedro Isaac Chávez López, dating back from 2014, is
going to be retired from the official package server in a couple of
weeks. Pedro signalled to us that the package isn't maintained anymore,
and the functionality of estimating an optimal Box-Cox transformation
for a single series is now covered by the newer BoxCoxFuncForm package
as well, after its recent update to v0.5.
(There's one (arguably minor) thing that users would have to do manually
now: For series with negative values, the old Box_Cox_Value package
shifted the series to the right, to the strictly positive region. Users
of the newer BoxCoxFuncForm package would have to apply this shift
themselves in a prior step, if it makes sense to do so.)
If for some reason you depend on Box_Cox_Value, please save a local copy
of the package for your own future use.
As always, if you have questions on the usage of the newer package,
you're welcome to ask them here.
cheers
