Panel Data: Linear Regression
About the Panel Data: Linear Regression
The Panel Data: Linear Regression task analyzes a class of linear econometric models
that commonly arise when time series and cross-sectional data are combined. This type
of pooled data on time series cross-sectional bases is often referred to as panel data.
Typical examples of panel data include observations over time on households,
countries, firms, trade, and so on. For example, in the case of survey data on household
income, the panel is created by repeatedly surveying the same households in different
time periods (years).
Note: The version of the task depends on what version of SAS/ETS is available at your
site. For example, if your site is running the second maintenance release for SAS 9.3,
SAS/ETS 12.1 is available, and SAS Studio is running version 1 of the Panel Data:
Linear Regression task. If you are running SAS 9.4, SAS/ETS 12.3 is available, and
SAS Studio is running version 2 of the Panel Data: Linear Regression task. The
difference between the two versions is the addition of new options in SAS/ETS 12.3.
Example: Linear Regression with Panel Data
To create this example:
Create the WORK.GREENE data set. For more information, see “GREENE Data
Set” on page 261.
In the Tasks section, expand the Econometrics folder and double-click Panel Data:
Linear Regression. The user interface for the Panel Data: Linear Regression task
On the Data tab, select the WORK.GREENE data set.
