Hi,
I've just re-read or read more carefully the earlier posts about the new
band plotting feature.
They all seem to talk about a center/width combination to be passed to
gretl. This would imply that the bands are restricted to be symmetric --
OK, I admit that you could reverse-engineer fake "center" and "width"
values if you have the lower and upper bounds of the band in the first
place.
But (confidence) bands are not symmetric in general. So I would vote for
the possibility to specify arbitrary center/low/high triplets instead.
Or am I missing something with this new feature?
Thanks,
Sven
