2
Getting Started
  • Open Eviews window
  • Create a workfile
  • Import data
  • Edit and Save data
  • View and plot data
  • View summary statistics
  • Generate new variables
  • Run simple regression

3
1.Open Eviews window-1
  • Click on the Eviews icon-Main Eviews window
  • title bar at the top, inlcluding menus such as
    File, Edit, etc.
  • command window immediately below the title bar.
    You can execute commands either by clicking on
    command buttons or by typing equivalent command
    into the command window.

4
1.Open Eviews window-2
  • Status line
  • At the bottom, providing additional
    information on the status of various settings of
    the program.
  • Work area
  • Between the command window and the status
    line, where the results of operations will be
    displayed.

5
2.Create a Workfile-1
  • Click on the File menu, then on New, and on
    Workfile - the most important object container in
    Eviews, which can be used to store data
  • In the window appeared
  • Choose the type of your data. For example, you
    can select Dated-regular frequency for
    time-series data
  • Input the start and end dates of your data
  • Name the workfile (optional
  • Click OK.

6
2.Create a Workfile-2
  • The workfile now contains two entries
  • c constant, where Eviews saves the intercept of
    the regression
  • resid residuals, where Eviews saves the
    residuals of last regression

7
3.Import data-1
  • Import from excel file
  • Open the file, make sure the observations for
    different variables are arranged in columns, with
    names on top. Copy the names of the variables,
    and remember the Upper left data cell (location
    of first data, i.e., A2), then close the
    spreadsheet.
  • In main Eviews window, after creating the
    workfile, click File, then Read Text-Lotus-Excel,
    and specify the location of data file.
  • In the opened dialog box, fill in the Upper left
    data cell, then past the names of the variables,
    click OK.

8
3.Import data-2
  • Enter data manually
  • click on Quick in the title bar, and then on
    Empty Group (Edit Series).
  • Next enter the variables, starting with the name,
    in the grey box to the immediate right of obs.

9
3.Import data-3
  • Import ASCII data form a textfile
  • Make sure the observations for different
    variables are arranged in columns, with names on
    top.
  • In the Eviews workfile window, click Procs, and
    Read Text-Lotus-Excel, then browse for location
    the text file.
  • In the dialog box, select from a range of input
    options.

10
4.Edit and Save data-1
  • Edit data
  • click the Edit/- button on the workfile
    toolbar, move to the observation in question,
    enter the correct value, and press Enter.
  • Paste data into word file click freeze, then you
    can copy and past.
  • Print data click Print button.

11
4.Edit and Save data-2
  • Save data
  • Save an entire workfile click Save in the
    workfile toolbar, or click on File and then
    SaveAs in the main menu.
  • Store individual series clcik Store in the
    workfile toolbar. If you need to retrieve the
    series, you can simply click on Fetch in the
    workfile toolbar.

12
5. View and plot data-1
  • View data
  • One variable double click on variable in
    workfile window, click on view, then spreadsheet
    or simply click on Sheet
  • Multiple variables in workfile window, select
    the name of variables needed, right click and
    choose open group view/spreadsheet

13
5. View and plot data-2
  • Plot data
  • One variable double clicking on the name of the
    variable, then click on View /Graph/Line in the
    resulting series window.
  • Multiple variables open the variables as a
    group, then click View /Multiple Graph/Line.
  • Edit double click on the graph or click on
    Options button to edit.

14
6.View summary statistics
  • One variable
  • Click the View button at the upper-left corner of
    the workfile, then click on Descriptive
    Statistics, and Histogram and Stats
  • Multiple variables
  • First open the variables as a group
  • View Descriptive Statistics in the group
  • View correlations

15
7. Generate new variables
  • In the workfile window, click Genr button, then
    specify the new variable using equation formula.
  • Alternatively, in the command line, use command
    genr to generate new variables. For example,
  • natural logs genr lqvettslog(qvetts)
  • genr unemplsqunemploymentunemployment
  • lagged variable genr lpriceprice(-1)

16
8.Run simple regression-1
  • In main Eviews window, click Quick, then Estimate
    Equation. Alternatively, in Workfile window,
    click Object, and New Object, then click
    Equation.
  • Equation Speciation write down the equation,
    then choose the method (usually least squares)
    and sample period.

17
8.Run simple regression-2
  • Saving equation using Name Option
  • Note If run linear regression, you may just
    input the name of the variables instead of the
    whole formula. First is the dependent variable,
    then write down all independent variables. (e.g
    Y c X1 X2 Xk)

18
8.Run simple regression-3
  • The interpretation of the coefficients
  • It indicates the effect of a unit change in the
    relevant variable on the dependent variable,
    holding all other factors constant (ceteris
    paribus).
  • Exporting table of results
  • Save table using Freeze/Name
  • Open table, select all, then copy and choose
    formatted, thus paste in word file.

19
8.Run simple regression-4
  • Test
  • Click View/Coefficient Tests/Wald-Coefficient
    Restrictions.
  • View results in the equation window
  • Regression output click View, then Estimation
    output
  • Residuals click View, then Actual, Fitted
    redisual
