Here are some resources that I have found useful to quickly learn using Stata:
- Stata tutorial from Germán Rodríguez at Princeton;
- Stata pages at IDRE, UCLA;
- Introduction to Stata from UNC;
- Two-page Stata from Andrew Grogan-Kaylor;
- Notes on Introduction to Stata and Advanced Stata Topics, from the LSE class on Stata for PhD students.
If you want to create maps with Stata (not the easiest thing to do…) there is a guide by Friedrich Huebler.
