Open the Excel file containing the data (example 2. XLS) 48 undated observations 4 columns (OBS, X, Y, Z) 3 variables: X, Y, Z 5

Enter or read data in Eviews File > New > Workfile 3. Click OK. 1. Choose “Undated or irregular”. 2. Specify 1 and 48. 6

Enter or read data in Eviews Choose Quick>Empty Group(Edit Series) 7

Enter or read data in Eviews Key in data 8

Enter or read data in Eviews Copy the data from Excel (A 2: D 49 together) to the Workfile Default series names 9

Renaming the series First minimize the data sheet Highlight ser 01 and right click mouse, and choose rename 10

Rename the series (ser 01 – ser 04) 11

Check if the variable names has been changed 12

Save data and results frequently to avoide loss of data File>Save. As Enter example 0. wf 1 13

Scatterplot of X and Y 1. Highlight x and y 2. Quick > Graph > Scatter 3. Order the variables 4. click OK. 14

Scatterplot of X and Y 15

Scatterplot of X and Y Use options to adjust the appearance 16

Scatterplot of X and Y Use Add. Text to adjust the appearance 17

Use Lines/Shading to adjust the appearance 18

Scatter plot after some formatting 19

Alternative way to do scatterplot of X and Y 1. Put X and Y in a group called gxy group gxy X Y 20

Alternative way to do scatterplot of X and Y 2. Generate scatter plot using the data group of gxy freeze(Figure 21) gxy. scat 21

Alternative way to do scatterplot of X and Y Double click figure 21 to view the plot 22

Scatter plot of X and Y 23

Generate a scatter plus a linear fit freeze(Figure 22) gxy. linefit 24

Double click figure 22 to view the plot 25

Scatter plot with linear fit 26

Group data for scatter plot group gzy z y 27

Create scatter plot, save in Figure 23 freeze(Figure 23) gzy. linefit 28

Another scatter plot (data group gzy) with linear fit 29

Run linear regression and save the results in table. A 1 equation table. A 1. ls y c x z (Y = c + b 0 X + b 1 Z) 30

Regression results (tablea 1) 31

Save all the results and data File > Save. As 32

Next time, we can open the workfile File > Open > workfile 33

We can continue to work on the data and plots… 34
