Statistics Made Easy 6.3: Testing U-Shaped Relationships in Stata

In this video, we explore how to test for (inverted) U-shaped relationships in Stata, a special type of moderation analysis. We will calculate interaction terms, marginal effects, and visualize the results.

For additional background reading, I recommend these papers:

Remember, the official Stata help files (type "help [command]" in the Stata command line) and the Stata forum (statalist.org) offer valuable support. Additionally, search engines (e.g., Google and Bing) and artificial intelligence tools (e.g., ChatGPT and Gemini) can assist you in finding the code you need.
