Datastream datatypes in eviews

Postby jgutman » Tue Nov 04, 2014 4:51 am

When I fetch Datastream series using the basic mnemonic, it works fine, but I haven't been able to figure out how to pull specific datatypes. For example, "lcpware" is lme copper warehouse inventories, and "ow" is the datatype for on-warrant. "fetch(d=datastream, link) lcpware" works fine, but it isn't clear how to specify "ow". Thanks

The normal syntax for fetching data from Datastream with a datatype is to place the datatype in parenthesis. For example

fetch(d=datastream,link) lcpware(ow)

However when I tried your particular series and datatype example I got a series of NAs.

fetch(d=datastream,link) ibm(p)

is a working example.

actually, I get something slightly different -- it ignores the "ow" datatype, and just gives me "lcpware"

I created a 5 day daily workfile and now all the values now look correct. It is possible the data is being frequency converted, but the following works

Code: Select all

create 5 2013 2014 fetch lcpware(ow) rename lcpware lcpware_ow fetch lcpware group g lcpware lcpware_og show g.line

When I do the same, I still get the same values for lcpware and lcpware(ow) -- and in both cases the underlying data is lcpware. I think the problem is on the DS side, I kicked it over to them.
Thanks very much for helping on this, Jason.

Try going here:
http://europe.dataworks.thomson.com/dat ... fault.aspx

enter your username and password. Set Source to Datastream and Instrument to LCPWARE (must be in all caps). Then press Start. Look at the data.

Now try setting instrument to LCPWARE(OW) and press start. The data was different for me. If it is the same in both cases for you, it is on the Thomson side.
