It seems that daily series in gretl databases was an idea that was
only
partially implemented and then never really developed. In today's git
and snapshots there are some relevant updates. You can now "store" daily
data in gretl db format, and read them back into a blank workspace, or a
matching daily workspace, or (via --compact=spread) into a monthly
workspace. At this point the GUI is only partially synced with these
changes.
Very good. Some things I noticed with this latest snapshot:
- in the idx file of the database the date format is ISO style:
YYYY-MM-DD, whereas appendix A.3 says one must use YYYY/MM/DD. I guess
the doc needs updating, or are there existing databases with that format?
- I can store 5-day and 7-day daily data alright.
- I can also store 6-day daily data (an idea which I got from the setobs
documentation) which then gets an "S" code, presumably for "special".
I
can even reimport that series into a fresh gretl workspace, and to my
surprise gretl recognizes it as 6-day data. I'm actually not sure where
it got the information from -- a clever combination of start and end
dates and the num of obs? Or is "S" actually for Six?
- The doc says the database description in idx can only be 64 characters
long. Why? Even the description of each series can be 128 chars.
Thanks,
