Hi all,
Using lists is a great time saver in gretl. I like using lists a
lot. It's still a bit hard to use them in the GUI, though. So.... I have
two feature requests.
1. I'd like to be able to choose a list in the specify model dialog
boxes in the GUI.
Also, it would be nice to have a button in the specify model dialogs
to take you to the define list dialog.
Better still: select variables from the main window via shift-click, ctrl-click or whatever, then right-click and choose "make this a list"
Excellent idea!
2. I'd like the ability to specify variables to be included in the
modtest --breusch-pagan test statement. (nothing to do with lists, but what
the heck). Something like
modtest z1 z2 --breusch-pagan
or even better
modtest zlist --breusch-pagan
I like this: however, there's a syntax problem; not unsolvable, but a bit annoying. At present, modtest has one optional argument (a scalar), mainly used in a time-series context. Allowing for a list makes syntax parsing a bit more complex. But then, a nice opportunity opens: how about replacing "add" and "omit" with "modtest <list> --add" and "modtest <list> --omit", respctively? Clearly, this would be massively backward-incompatible, so obviously it would be a 2.0 thing; still, in the meantime we could keep the two.
I like this one too. It fixes the add/omit 'problem' -- as in what to do with them. I wonder if a more flexible version of modtest that could take more inputs would help? To maintain backward compatibility it would have to have a new name -- definitely a version 2.0 thing, though. On the other hand, it would be confusing trying to figure out which to use... so maybe not....
