I repeatedly find myself looking in the built-in dataset collection to open a
dataset with a certain structure (e.g. for testing, or for teaching). I find
it hard to locate for example a panel dataset with T > N. Couldn't that kind
of information be displayed in additional columns? (So far I see only "File"
and "Summary" there.)
I can see a case for a simple additional column, say "dimension",
which could have, for example, "n = 1200" for a cross-sectional
dataset, "T = 96" for time-series, or "N = 20, T = 30" for a panel.
Here's a fairly simple rainy-day task for somebody: go through the
supplied data files (maybe in the first instance just the ones under
the "Gretl" tab) and compose a little text file on the same format
as the existing "descriptions" file, so for instance:
"abdata","N = 140, T = 9"
"anscombe","n = 11"
"arma","T = 624"
If anyone does that, I'll be happy to arrange for it to be picked up
in the same way as the current "descriptions" file and displayed in
I'm aware that we _could_ read that info automatically from the gdt
files, but in the interest of responsiveness I think I'd rather not
(gunzip and) parse a bunch of XML files on the user's accessing a
tab in the data browser -- though I suppose that might be worth the
experiment (how long does it really take?). Downside for me: I would
have to code that experiment!
