- I'm somewhat surprised by the these two postings. I think that
- it's been mentioned more than once that EconData is provided by
- INFORUM, a non-profit research group at the University of Maryland.
- INFORUM does not receive funding to provide EconData. The data
- that you'll find on EconData are data that were needed by INFORUM
- for their forecasts. The data are updated as needed and passed
- along thereafter. One hopes that something like EconData (if not
- EconData itself) will someday be funded so that up to date
- information can be provided.
-
- The Commerce Department's EBB BBS may often provide more up to date
- information, but you may notice that these data are often not in
- the form of time series and provide very little history. INFORUM
- uses EBB to update some of their banks, but this can be a tedious
- process. The files on the EBB are mainly ascii files of tables
- which have come from a recent publication. The lotus files which
- are there are usually just these same ascii files after being
- imported. These are not a very efficient way of storing data.
- This efficiency of storage (especially for large data sets) is an
- important issue when the data are to transferred by either modem or
- internet connection. The larger a file, the longer it takes to
- send.
-
- Dr. Almon has taken this into consideration in how he designed his
- data banks. The G data banks are very efficient in their storage
- of data. He is also continually looking for the latest and most
- efficient file compression software. He takes a great interest in
- shortening file transfer times. When a bank is updated on EconData
- you will often find provided an update bank, so that the user
- doesn't have to waste the time to update the download the complete
- bank each time he/she needs it.
-
- I also don't find the format of the data on EBB very appealing.
- Although many software can make use of the lotus and ascii files,
- I've always found that it takes a lot of editing to get these files
- into a form worth using.
-
- Perhaps you may have missed it, but PDG can write the specified
- series to a lotus or ascii series from any of the data banks and
- without the table headings and other nonsense. In fact, new
- commands have recently been implemented to produce output in rows
- as well as columns.
-
- I'm sorry to write such an adamant reply, but I greatly appreciate
- the efforts that Dr. Almon has made. And although I might have
- differences with how PDG operates as an econometric package, I am
- very impressed by the data storage capabilities. Also, PDG is far
- more than I would ever expect in a FREE package.
-
- Thanks for letting me clear the air,
