Statistics Made Easy 3.1: Data Preparation in Stata

In this tutorial, we learn how to prepare data for statistical analysis using Stata. This includes creating and deleting variables, labeling variables, and working with numeric, categorical, string, and date variables.
For additional background reading on nonlinear transformations of variables (e.g., logarithmic transformations), I recommend this paper:

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.
You can download the datasets, additional explanations, and the Stata "Do Files" for the tutorial by following this link:
