Study Notes

Creating a Time Series Workfile

A time series workfile can be created by importing data from an Excel file, where the first column contains dates and the next columns contain information on main US macro variables.
To create a workfile, click File → Open → Foreign Data as Workfile, select the directory, and open the file.
The Excel Read dialog appears, and clicking Finish loads the data into the workfile.
EViews automatically detects the time series data and indexes the workfile by date.

EViews Workfiles

EViews workfiles are place-holders of EViews objects and are required for any work in EViews.
A workfile can be created by either structuring a "blank" workfile or by reading from a foreign source.
Every workfile contains one or more workfile pages, each with its own objects.

Describing the Structure of a Workfile

To create a new workfile, the structure of the data needs to be described, including the frequency, start and end dates, and number of observations.
There are three general types of workfile structure: Dated (regular frequency), Unstructured/Undated (mostly cross-sectional data), and Balanced Panel (panel data).
A simple workfile with one page has one structure type, while multiple page workfiles may have different structures.

Creating a Workfile

To create a new workfile, click File > New > Workfile… and specify the workfile structure type, date specification, and workfile name.
The Workfile Create dialog box opens up, where the workfile structure type, date specification, and workfile name can be specified.
The workfile structure type can be Dated, Unstructured/Undated, or Balanced Panel.
The date specification includes the frequency, start date/time, and end date/time.

Creating a Dated Workfile

To create a dated workfile, select Dated-regular frequency from the drop-down menu of "Workfile structure type".
Specify the frequency, start date, and end date of the data.

Creating an Undated Workfile

To create an undated workfile, select Unstructured/Undated from the drop-down menu of "Workfile structure type".
Specify the number of observations in the "Data Range" field.
