Maybe so, but I'm interested to see if we can inflect the
"aggr"
apparatus in "join" such that it handles an n:n join.
open awm.gdt
join hamilton.gdt PIT* --data=PC6IT
Hmm, perhaps --filter could also be used with the canonical dates? For
example for PIT_m2 we want to have those rows which have an ISO date
with Feb 1st, like this: ????0201
So one could check wether: (rowdate - 201) % 10000 == 0
Of course, a lot of special casing would be necessary with the different
frequencies...
About databases:
Hmm, not sure. I think that daily series (at least) are supposed to
be
supported in gretl databases.
Yes as per appendix A.3 of the guide. (Weekly isn't mentioned there.)
But I can't remember if there's any extant
database that includes daily data;
I couldn't find any.
been tested in a long time. The "store" doc is deliberately
conservative; I don't know offhand if it's too conservative.
I get error messages if I try to store weekly or daily data to a
database. So the 'store' doc looks right. The question then is how to
actually create a database with daily data?
