[Gretl-users] contrib. package Box_Cox_Value to be retired
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
sven
