This code accompanies the Aptech blog Introductionn to Difference-in-Differences which was published on 03/29/2019.
The program files require a working copy of GAUSS 18+. Many can be run on earlier versions with some small revisions.
Two program files are included:
- did_calculations.gss - This file contains the code for computing the difference-in-differences calculations reported in the blog.
- did_plots.gss - This file produces the plot included in the blog.
