EView Help ã   In EViews window toolbar: Click Help , then click EViews Help Topics…   Turning Off Annoying Naming Questions ã   In EViews window: click Options , then General Options   ã   Under Windows,   click Window behavior   ã   In the Warn on Close box, uncheck Groups  and Equation-SysVAR-PoolModel  boxes Opening and Closing Workfiles A Workfile from a PDF File Open a Workfile from a PDF File ã   Click inside the red EViewsLink box ã   In the File Download window: Select Open   Close a Workfile from a PDF File ã   In EViews window: Click File , then Exit   ã   In Workfile window: Click No  in response to the save changes made to workfile A Workfile Stored on Your Computer Creating a New Workfile on Your Computer from an Excel File ã   In EViews window toolbar: Click File  and then Foreign Data as Workfile…   ã   In Open window: Select the Excel file and click Open   ã   Follow the instructions provided by EViews Open a Workfile on Your Computer ã   In EViews window: Click File, then Open, then Workfile ã   In Open window: Highlight filename, then click OK   Saving a Workfile on Your Computer ã   In EViews window toolbar: Click File  and then Save   Close a Workfile on Your Computer ã   In EViews window: click File , then Close   ã   Click Yes  to save the changes made to workfile, No  otherwise (typically, you will want to save your changes by clicking Yes )   2 Analyzing One Variable Descriptive Statistics (Mean, etc.) of a Single Series ã   In Workfile window: Double click series ã   In Workfile window: Click View , then click Descriptive Statistics & Tests, then click the desired option (usually Histogram and Stats or  Stats Table ). NB: the standard deviation that is printed assumes that the data are a sample rather than a population. To calculate the standard deviation of a population, click on Stats Table  to obtain the Sum Sq. Dev.  (sum of squared deviations from the mean) and then divide by Observations  (the number of observations). Graphing a Series ã   In Workfile window: Double click series ã   In Workfile window: Click View , then click Graph… ,   then click the desired option Analyzing Two or More Variables Descriptive Statistics of Two or More Series ã   In Workfile window: Click to highlight first series, then click while depressing <Ctrl> highlight the second series, third series, etc. ã   In Workfile window: Double click on a highlighted series ã   In Workfile window: Click Open Group   ã   In Workfile window: Click View , then click  Descriptive Statistics, then click Individual Sample  or Common Sample  NB: there is no difference between common sample and individual samples unless missing values are present in the workfile. Common sample eliminates all observations in which there is one or more missing value in one of the series; individual sample does not do so. Covariance and Correlation Coefficient Matrices of Two or More Series ã   In Workfile window: Click to highlight first series, then click while depressing <Ctrl> highlight the second series, third series, etc. ã   In Workfile window: Double click on a highlighted series ã   In Workfile window: Click Open Group   ã   In Workfile window: Click View , and then click  Covariance Analysis…   ã   In the Statistics box: Select the Covariance checkbox for covariances and/or Correlation for correlation coefficients; then, click OK   Graphing a Scatter Diagram of Two Series ã   In Workfile window: Click to highlight first series, then click while depressing <Ctrl> to highlight the second series ã   In Workfile window: Double click on a highlighted series ã   In Workfile window: Click Open Group   ã   In Workfile window: Click View , then click  Graph…, click Scatter , and then click OK     3 Generating a New Series ã   In Workfile window: Click Genr   ã   In Generate Series by Equation window: Enter the formula for the new series in the Enter equation text area; for example, Sum of two series: NewSumVar = OldVar1 + OldVar2 Ratio of two series: NewRatioVar = OldVar1/OldVar2 Dummy variable: NewDummy = OldVar > 10000 ã   Click OK  NB: The only permissible characters in a name are letters, digits, and the underscore(_); blank spaces are not permitted. Some series names such as “sin”, “cos”, “c”, “d”, and “res” are reserved.   If you provide EViews with an improper name, EViews will not generate the series and an “Error Message” box will appear; after clicking OK, you can try a different name.
