Introduction

This Eviews-introduction is part of the material for a basic course in Econometrics. It should
be used together with a copy of the Eviews software, a textbook and the corresponding
datasets. The datasets will be made available to all students via the computer network.
Since Eviews, “Econometric Views” is widely used in the Econometrics curriculum andnumerical examples in econometric textbooks are often based on Eviews results, we havechosen the package for this course.
During the course the student has to make a number of computer exercises in order tounderstand the methods in practice. EViews 4 is used to solve the exercises. The faculty of
Economics has a student licence for EViews 2.0, so EViews can be used at home too. This
lower level of EViews does not present major problems for this course. Eviews 2.0 is anolder program and does not always work well with long directory names and file names. So
you may have to change the names of some folders and files at home. A more recent version
of Eviews (3.1) for students is available for use at home for 30 Euro. Ask the teacher.
Eviews 5 has become available in 2004, but Eviews 4 commands should continue to work
also in Eviews 5. A student version of Eviews 5 is not available.
Eviews and its documentation are only available in English. The Faculty of Economics
also employs English versions of the Windows operating system. That is why we havenot attempted to write this introduction in Dutch. Please look up English words in the
documentation that you really don’t understand. After following the instructions in thisdocument hands-on, you should be able to learn the operation of other procedures in Eviews
more easily.

The software EViews

2.1

Introduction

EViews, Econometric Views, is described in this text. Eviews is a widely used programin education, government and industry. It originated from the program TSP, Time Series
Processor, http://www.tspintl.com. Nowadays, Eviews and TSP coexist, with Eviews
specializing in user-friendliness and TSP specializing in speed, scientific documentation andnumerical accuracy.
Originally intended for time series data, Eviews is now also fit for the analysis of crosssection data and panel data. Eviews provides most standard econometric techniques. The
Eviews-terminology for its procedures follows the standard of most Econometrics’ textbooks.
This terminology may differ slightly from the standard statistics-terminology. Moreover,some standard statistics’ procedures like the BoxPlots, are not (yet) implemented in Eviews
4.
EViews produces pictures and tables that can easily be imported in word processing
systems like Word, Scientific WorkPlace or MikTex.

2.2

EViews Basics

Eviews is started and closed like other Windows-programs. In a standard installation you
will find it via the Window Start-Menu on the bottom of your screen, for example via
Start-Programs-Eviews-Eviews 4. The Main Eviews Window will pop up. Figure 1 shows
this menu. The Main Menu options File, Edit, Window and Help follow the standard
Windows-conventions. Objects, View, Procs, Quick and Options incorporate the special
Eviews-features. The bottom line, or status line, of the main window provides additional
info on the status of various settings of the program. The only relevant part at this pointis the Path: information. This tells you in which folder Eviews looks for input files first.

Figure 1: Eviews Main Window
Eviews Help
The Eviews Help-system is comprehensive, it encompasses nearly the entire user’s guide.
Figure 2 shows the main help topics for Eviews novices.

Figure 2: Eviews 4 Help: Table of Contents
The Chapters of the Eviews Windows Help books can be long. It is not possible to do a
keyword search within a chapter in the Windows Help system. However the Help system
also contains .pdf files which can be browsed by Chapter and which can be searched using
Acrobat Reader, using Ctrl-F or the “binocular” icon within Acrobat Reader.
Use the Help-function later to explore other options of EViews that are not discussed
in this document.
Standard Windows functionality
The “Introduction to Eviews” of the Eviews-Help also explains Windows Basics forpeople who are not familiar with the Windows-system.
Eviews works as a standard Windows-program, like Windows-Explorer. It has theadvantage that all menus are text based, so you don’t have to learn the meaning of new
icons. Pointing and clicking with the mouse is sufficient to browse through all the options
and to perform many tasks.
In standard circumstances left clicking on an item selects an Eviews object, right clicking
a selected object opens a menu. Double clicking an object opens the specific EconometricView of an object. Many of the standard Windows editing-keys Ctrl-C (Copy), Ctrl-X(Cut), Ctrl-V (Paste), ctrl-Z (Undo last edit action) work as expected.
A general Undo button to correct your own faults is not available and the program is
not entirely robust on the network. Therefore: save your results regularly, as it is not
impossible that the program crashes unexpectedly and all what has been done is lost!

2.3

An Eviews Basics Demonstration

By repeating the actions of this Demonstration you will get to know most of the basic
concepts of Eviews: Workfiles, Objects, Series, Sample, Expressions, Series, Auto-Series,
Groups, Graphs, compare the table of Contents in Figure 2. Knowing these basics is necessary to find your own way in Eviews later on. We discuss how to
1. create Workfiles, setting a Sample and Import Data
2. save Workfiles
3. navigate most of the Eviews-windows
4. create simple Eviews Objects like Groups
5. use Expressions in the Command window
6. perform standard data tranformations
7. create, adjust and export Graphs
At this stage of the course we cannot use econometric procedures, but some preliminary
runs can be done with the data that are provided with the book. We can perform astraightforward data analysis: graphs can be made, correlations can be computed, data canbe seasonally adjusted, etc.
2.3.1

Eviews Workfiles and Data Import

The Chapter titled “Workfile basics” of the Eviews Help-system states: “At the heart of
the EViews design is the concept of an object. In brief, objects are collections of related
information and operations that are bundled together into an easy-to-use unit. Virtually allof your work in EViews will involve using and manipulating various objects. EViews holds
all of its objects in object containers. You can think of object containers as filing cabinets ororganizers for the various objects with which you are working. The most important object
container in EViews is the workfile and your first step in any project will be to create a newworkfile or to load an existing workfile into memory”.
Therefore, the workfile is the starting point in EViews. We create a new workfile forevery new project. Within workfiles one works with objects, like series, equations, groups ofvariables, graphs, tables, etc.. All these objects are part of the workfile. So the first thing to
do in EViews is to create the workfile and to import data. This will create the first objects:
a number of series. In the first session one has to import data into the workfile. An existing
workfile can be opened in any EViews-session later on.
EViews can import data in a variety of formats, like ASCII-text and Excel. To import
the data, one has to know how the data has been organized in the file. The data files forthis course have the standard spreadsheet organization. The observations for the different
variables are arranged in columns, with variables names on top.

4

2.3.2Creating a Workfile

Here is how you start working with Eviews on the ASCII dataset in the text file into
Macro95.dat, which is available in the folder DataCarlsonThorne. This file contains quarterly data on 22 US macroeconomic variables running from 1959.1 to 1995.2.
(Re)Start EViews in Windows. Click on File and New ; Then click Workfile. A window
appears with questions about the data: the frequency and the sample period. Click on thecorrect frequency (Quarterly) and fill in the correct Start date and End date. Click ‘OK’and change the name Untitled in Macro95, by using File SaveAs. Choose a directory where
you have the permission to save your results! The workfile gets the Eviews-extension .wf1.
The new workfile is now saved as Macro95. Do not forget to tick(mark) Update Default
Directory. This changes the Path-Setting in the status line at the bottom of the Eviews
Window. EViews will start the next session in the same directory you have just chosen,
which is very convenient.

2.3.3

Importing Data in Eviews 4.1 or lower

Now data can be imported in the workfile. Click on Procs and Import and Read Text-LotusExcel (in our situation the data are in a text file) and browse for the file, Macro95.dat thathas to be imported. Click ‘OK’, and Eviews asks you to select from a range of inputoptions, see Figure 3. EViews asks whether the data file is organized in Columns or inRows (formerly called: by observation or by variable). If the data file contains the namesof the variables, only the number of variables in the file has to be filled in. In our case there
are 22 variables, the first one being a “date”-variable, so we always know the dates of thecorresponding observations in the same row of the data set.

Figure 3: Importing ASCII data from a textfile
There is also a ‘preview window’ to check that the correct data will be imported and to
see that the data really are organized in columns. If the data are not neatly organized ina matrix, do not mark ‘File laid out as rectangle’.

5

If your ASCII-data are not in the right format, you should edit them in a text-editor.
Eviews contains a primitive text editor. Select File-Open-TextFile from the main menu
and open Macro95.da0 (a copy of Macro95.dat, since the basic version of Eviews 4 does
not allow opening .dat files in this way). to see how it looks in a text editor. Much better
freely availble text-editors exist, see e.g. OxEdit, www.oxedit.com, an editor that is also
installed in the computer lab.
2.3.4

Checking Imported Data and Saving the Workfile

If all has been done correctly, the names of the variables appear in the workfile window,
otherwise wrong names like ser01, ser02, etc. are seen in the workfile. The different
variables are called Series in Eviews, even if the observations are not ordered according totime, in which case Eviews labels them as undated or irregular series. Series are Eviews
Objects that we use most often. Statistical and econometric methods can now be used toanalyze the variables. Extra data can be imported at a later stage.
Double click a series name (with the left mouse button). A new window with its own
buttons appears. See the options under View, check a spreadsheet View and a graphicalview of the Series and see whether the data have been imported correctly.
If your are satisfied with the imported data you should Save the Current Workfile
using File-Save from Eviews Main Window. To reuse your workfile in a next session,
start again by clicking on File. Then the names of the last used workfiles are visible ina ‘history list’ and one can select directly a workfile from this list. It is also possible todouble click on the name of the workfile in the “Microsoft explorer” or “Total Commander”(http://www.ghisler.com/. Then EViews starts with that workfile if the extension (.wf1)
has been associated with the EViews program in your file browser. If this is not the case,
Right-click on a .wf1 file and look at the Properties, then look under the General tab on
the line with Opens with and browse to the executable Eviews5.exe (if your Eviews versionis 5).
2.3.5

Creating Workfile from a ’Foreign’ Excel file in Eviews 5

Since Eviews version 5 it is also possible to Open excel data, while simultaneously creatinga Workfile. Use File-Open-Foreign Data As workfile from Eview Main Window. Figure 4,
5, 6 show what happens if you open macro95Eviews51.xls in that way. case. The workfile
and the group with variables are automatically created. The dates are stored according toEviews and associated labels are created in the label series OBS, if the .xls file was createdwith Eviews 5 using the Eviews date format.
2.3.6

Eviews menus and Creation of Simple Objects: Groups and Equations

Once you have successfully loaded data into a workfile it is time to browse through thespecial options of the main Eviews menu of Figure 1 again.
The Object-drop-down menu allows you to create all types of new objects and to rename
and delete existing objects. You can create a new Series if you want to type the data in
6

Figure 4: Open .xls Data as a workfile, step 1

Figure 5: Open .xls Data as a workfile, step 2
yourself.
The Quick -menu provides quick shortcuts for experienced Eviews users. A useful application of the Quick -menu is provided in §2.3.8
The drop down menus under View, Procs in the main Eviews menu are context sensitive:
The range of options depends on the object(s) selected at the moment of the analysis.
Similar View and Procs menus are also available in the windows of the objects themselves.
Check this out for the a Series-object. Double click on a variable name in the Workfilewindow: an Eviews-Series-window pops up. Under View you’ll find the graphs and descriptive statistics that we need in a first stage data analysis, under Procs you’ll find moreadvanced options like Exponential Smoothing. Note that the same options are now available

7Figure 6: Open .xls Data as a workfile, step 3
under View and Procs in the main Eviews menu.
Within a workfile it is possible to create other Objects like Groups of variables. EviewsGroups are extremely useful objects. The Eview-Help says: “A group is simply a list ofseries identifiers. It is not a copy of the data in the series. Thus, if you change the data forone of the series in the group, you will see the changes reflected in the group”.
A group is created very easily. With the left-handed mouse button you select one series
first. To create a group more series can be added to the selection by keeping ‘Ctrl’ pushed
down and clicking with the left-hand mouse button on the relevant variable names, after
which it becomes a group by selecting Open selected (under View ), One window and Open
group. See also Figure 11 below, which shows an example of a group selection in the(background) Workfile-window.
If you want to specify an equation-object you should click on the name on the left-handside variable of the equation first. When you specify a regression equation later on it has
to be the first variable in the list.
It is also possible to click on the selected variable names with the right-hand mousebutton. Under View and Procs many possibilities arise to analyse the group (group statistics, various graph options, etc.); also regression equations are simply formed. After aprocedure has been applied (e.g. least squares) one can proceed with the analysis with new
possibilities given under View again (e.g. residual tests, coefficient tests).
The best way to learn the various possibilities of a procedure is to click on the various
buttons and to see what the possibilities are for the object in question. The structure
is logical and the help function is often adequate, provided you know the basic terms antechniques, of course.
Remember to save the workfile at the end of the session, so that everything what has
been done (transformed variables, equations, maybe groups etc.) is available in the next
session.
Each result (object) can be sent to the (laser) printer by clicking on Print in the toolbar

8

of that particular window, but it is better to export them to another program like Wordand make a simple report, before sending the results to the printer.
2.3.7

Command Window, Data Transformations and expressions

Transformations can most easily be specified in the white top-window, the so-called Command window. Type
series lgcq = log(gcq)
which generates a new series lcgq (after you press the Enter-key) and computes the logs ofthe consumption series gcq or use
series dgcq = gcq - gcq(-1)
which takes the first differences: it subtracts consumption in quarter t−1 from consumptionin quarter t. Typing
show dgcq
in the Command-window brings up the Series-Window of dgcq. This is a quick way to start
checking whether your transformation was successful.
You can also transform series by clicking on the button Genr in the workfile-window(then e.g. only lgcq = log(gcq) has to be specified). Many other Eviews Expressions:transformations, functions and operators are available, see the Function Reference of themain Help(-Reference) menu.
The Command Window keeps record of the commands by maintaining a ‘history list’.
This can be an advantage if similar operations have to done repeatedly. Old commandlines can be selected, adjusted and “rerun”: simply select the line in the command window
and press the Enter -key. Most procedures can be applied in the command window. The
Command reference of the main Help-menu provides all the commands.
Once you know some commands this can save you time. For example: a quick way to
re-import the data is to typeread macro95.dat 22
in the command window, provided the file macro95.dat is in the current Eviews-Path (seestatus line at bottom Main Window).
After generating many Eviews-subwindows it is sometime hard to find the command
window on your screen. You can always retrace the command window by clicking Window
on the main menu of the main Eviews window. The command-window is always no. 1 inthat list.
2.3.8

AutoSeries, Changing Data points

It is not always necessary to transform variables and save the results in a separate series.
Transformed data enlarge the contents of the workfile. It is also possible to use the AutoSeries (Automatically generated Series) feature of Eviews. For example, the specificationofd(gcq)
in the specification of a group or in the specification of an equation refers to the first dif-9

ferences (i.e. the changes over 1 period) of gcq, without generating observations in a newvariable permanently.
We shall see how this works by looking at the effect of a change in one of the observationsof the series gcq on the “Auto-observations” in the AutoSeries d(gcq):
Generate a new group consisting of gcq and d(gcq): Typegroup transgcq gcq d(gcq)show transgcq
in the command window. A new group, titled transgcq has been formed. Open the Spreadsheet View of transgcq: Click on View -Spreadsheet in the Group window of transgcq.
Edit the values of one of the observations of gcq: Click on Edit+ in the Group windowof transgcq, click on the cell of gcq that you want to change. The corresponding value
appears near the top of the window. Change the value and push Enter on your keyboard.
The corresponding values of d(gcq) change as well! Note that you cannot edit the valuesof d(gcq). Now you know why.
Note that you also could have used Quick -button of the main menu to bring up theprevious spreadsheet view. Use Quick -Show and type gcq d(gcq) in the resulting Show window and press OK. You can then change the name of the group by pushing the Namebutton in the group-window and entering the name transgcq
AutoSeries can also involve more complicated expressions like d(log(gcq)), which computes the first differences of the logs of gcq.
2.3.9

Examples of EViews output: Graphs and export Graphs to WordFirst an example is given of Multiple Graphs, Line in an EViews Group window. The series
gcq and gidpq have been opened as a group first. These graphs are then created in thegroup window under View. See Figure 7. These graphs should correspond to Figures 17.1

Figure 7: Multiple Line Graphs from Group Window
10and 17.2 on pages 826 and 827 in the book of Carlson and Thorne. Check the sample ifthey do not correspond.
In order to use the resulting picture in another program you should save it as a Windowsmetafile with the extension .wmf : Use the Copy command under Edit in the main menu ofthe main Eviews-window, and choose Save Metafile to disk or Copy to disk file, choose the.wmf format, then select a directory and choose a name, for example eviewsgraph1.wmf.
The option Copy to clipboard is not advised.
The picture can subsequently be imported in a Word document using Insert-PictureFrom File. See Figure 8

Figure 8: Inserting Eviews picture in .wmf format into Word
You can also “Edit” the graph with Eviews. Labels can be dragged to another place
to a new place in the graph: Click on the label, hold the mouse button pressed and movethe label. The label text can been changed as well: Double click on the label or use theright-hand mouse button.
Clicking on the picture with the right-hand mouse button (or double clicking with theleft-hand button: gives more options) produces an ‘Options window’ to change the general
outlook for different types of graphs, like a regression line in a scatter diagram or a zeroline in a line diagram. See Figure 9 for Eviews 3 and Figure 10 4 for Eviews 4. . .
2.3.10

Scatter diagram

To create a scatter diagram select in the ‘Group window’: Graph, Scatter and the scattertype. Optional is the ‘regression line’. In Figure 11 there is no regression line. ;11

2.3.11

Eviews Tables, editing and Exporting Tables to Word

At the end of this demonstration we show how to generate, edit, save and export numerical
output of Eviews.
(Re)Show the group transgcq that we created in the section on Autoseries. Look
for transgcq in the Workfile-window, or create it as a new group using Quick -Show andentering gcq d(gcq).
We create descriptive statistics from the pull-down menu under View in the Groupwindow: View -Descriptive Stats-Common Sample. The standard descriptive statistics of12

Figure 11: A scatter plot from the Groups Window
Eviews appear. See Figure 12.

Figure 12: Descriptive Statistics in a Group Window
Suppose now we want to edit and export this output. Then we should push the Freeze
button of the Group-window, or we could use Object-Freeze Output from Eviews’ main
menu. A Table-window pops up in a spreadsheet format. You can edit the output of thetable after pushing the Edit+/- button in the Table-Window. You can also change theappearance by changing the font and cell-width in the table. Once you are satisified withthe results you may want to export them to Word. First select the part of the table thatyou want to export with your mouse. Then export this part of the table using Edit-Copy
from the main menu of Eviews, see Figure 13. Eviews will ask whether you want to export
13the numbers formatted or unformatted. Choose formatted if you do not want to do further
computations with the numbers.

Figure 13: Exporting contents of an Eviews Table
Finally, import the Eviews-output in Word using Edit-Paste. See Figure 14. In Windowslanguage the last operations are described as: “Copy the contents of the Eviews-table tothe Windows-clipboard. Paste the contents from the Windows-clipboard into your Word
document.” The Paste-icon on Word’s main toolbar, shows a picture of the clipboard anda sheet of paper being removed, see Figure 14.

2.4

Advanced use of Eviews Help Examples: Maximum Likelihood

The help files for advanced objects often describe two ways to estimate models. The first(user manual) examples show how to create an object using menus and then tell what
to enter in the Object Window. Many other (reference manual) examples just tell you
the Eviews-commands, i.e. the commands that should be entered in the command
window. Here we describe how to use the Eviews Help examples for the LogL (loglikelihood)object and the corresponding ml (maximum likelihood) function, that is the most importantmember of this object. For user manual help, see Help-Contents -The Log likelihood (LogL)
Object. For reference manual help, see Help-Help Reference-Object Reference-Logl.

In order to use the examples of the manuals we have to create a workfile and example series.
We do this preparatory work in the command window:
create a 1900 2000
series x = 3*@rnorm
series z = 2*@rnorm^2+0.2
series y = x + z + @rnorm
Now we can start to apply the examples of the basic Eviews user Help system. The firstexample creates the loglikelihood using the main menu. This is an example of the type thatyou find near the beginning of the Help Chapters by user tasks and estimation methods in
the Contents Index of the Help-Eviews Help topics System.
To create a LogL Object use the menus Object-New Object-LogL.
Then you should enter the following lines into your log likelihood object, to be more
specific: in the Likelihood Specification View of the LogL object.
@logl logl1
res = y - c(1) - c(2)*x - c(3)*z
var = c(4) * z^c(5)logl1 = log(@dnorm(res/@sqrt(var))) - log(var)/2
param c(1) 1 c(2) 1 c(3) 1 c(4) 1 c(5) 1
Then simply click the Estimate button in the likelihood window toolbar to open the Estimation Options dialog. By default, EViews uses the values stored in the coefficient vector,(c()), prior to estimation. The default values are zero, which results in zero values for thevariance series var, which makes that the series of loglikelihood values logl1 cannot becomputed and initial estimates cannot be obtained. If a param statement is included in thespecification, the values specified in the statement will be used instead. This is a necessary
addition to the Eviews example.

The second way is to create the loglikelihood object (i.c. with name hsmodel), add its
15

members (i.c. the series logl1, res and var) and do the estimation only by commandsin the command window. These commands can also be used in Eviews programs.
logl hsmodel
hsmodel.append logl1
hsmodel.append res = y - c(1) - c(2)*x - c(3)*z
hsmodel.append var = c(4) * z^c(5)hsmodel.append logl1 = log(@dnorm(res/@sqrt(var))) - log(var)/2
hsmodel.append param c(1) 1 c(2) 1 c(3) 1 c(4) 1 c(5) 1
hsmodel.ml
This is an example of the type that you find in the Reference Manual: Help-Help Reference
and that you find near the end of the Help Chapters by Estimation Method in the Contents
Index of the Help-Eviews Help topics System. Remember that these (object oriented) commands (with dots) should be typed in the Command Window! Window -Command.
