Introduction to Difference in Differences (DID) Analysis

• Difference-in-Differences (DID) analysis is a useful statistic technique that analyzes data from a nonequivalence control group design and makes a casual inference about an independent variable (e g an event treatment or policy) on an outcome variable • The analytic concept of DID is very easy to comprehended within the framework

A separate manual (Graphics) is devoted to the topic only. Since STATA works in a Windows format, it allows you to cut and paste the data into other Windows-based program, such as Word or WordPerfect. Finally, there is a warning about the limitations of this tutorial.

How do you transform variables in Stata?

In STATA you transform variables by using the “gen” (as in generate) command. For example, Chapter 8 of the Stock/Watson textbook introduces the polynomial regression model, logarithms, and interactions between variables. Let us reproduce Equations (8.2), (8.11), (8.18), and (8.37) here. The following commands generate the necessary variables2:

How do I order Stata?

Perhaps the most useful of these are the User’s Guide and the Base Reference Manuals. You can order STATA by calling (800) 782-8272 or writing to service@stata-press.com. In addition, if you purchase the Student Version, you can acquire STATA at a steep discount.

What does VCE do in Stata?

The command vce asks STATA to print out the estimated variances and covariances of the estimated regression coefficients. The command gets STATA to carry out the joint test that the coefficients on str and expn_stu are both equal to zero. 2) The second new command is in the analysis of Table 7.1 on page 224 of Stock and Watson (2018).
