Seventy-Six Stata Tips

Since 2003, the Stata Journal has included Stata Tips on special issues in data analysis with Stata. Seventy-six Stata Tips, 2nd Edition compiles these useful guides into a compact tome for ease of reference. In keeping with the Stata spirit, Tips are from Stata users and StataCorp employees alike and will serve as guideposts for both new and experienced users.
