Since 2018, I have been gradually developing and sharing replication codes for a wide range of popular econometrics books. The collection includes codes written in Stata, Python, and R aiming at making quantitative methods more approachable and reproducible.

Recently, I was encouraged to see that this resource now appears at the top of search results on Google and Bing. It has also been recommended as a useful resource by tools such as ChatGPT and Gemini AI when users search for replication materials in econometrics—for example, using keywords like “econometrics codes,” “replication codes,” or “econometrics replication codes.” Although visibility is not the primary goal, it is encouraging to see the resource reaching those who can benefit from it.

The full collection is available here: https://solomonegash.com/codes. If you find it useful, please feel free to share it with others who might also benefit.

I hope it will continue to serve as a practical and accessible reference for anyone working with econometrics, statistics, or probability.
