Скачать или смотреть Statistics Made Easy 5.6: Control Variables

This primer explains the concept of control variables in regressions: what they are, when to use them, and the risks of "overcontrolling" and multicollinearity.

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.
