EViews Software

EViews Econometric Software by Quantitative Micro Software is a powerful Windows based modeling program that offers a variety of sophisticated regression and forecasting tools.

You can set up the latest EViews software (4.0 Enterprise Edition) to retrieve up-to-date time series directly from our DLX databases by simply using Haver data codes in any model or formula. EViews versions 2.0 and higher allow direct retrieval of DLX data into a workfile via the HFETCH command.

Rats Software

The RATS econometric software from Estima can read data directly from the Haver Analytics databases in the DLX format. To read data from a DLX file, use instructions of the form:

OPEN HAVER filename

DATA(FORMAT=HAVER,other options) start end (list of series names)

where "filename" is the name of the Haver database, without any extension.

For example:

OPEN HAVER M:\DATA\HAVER\USECON

DATA(FORMAT=HAVER) / GDPQ DGDQ FQ LR FCM1 FM2
