About

Welcome to my Stata guide! I first started putting this together when tutoring / teaching classes on statistics and econometrics for public policy while a grad student at the Woodrow Wilson School at Princeton. I'm continuing to update and expand it as my contribution to the internet.

I use Stata on an almost daily basis at work. Mostly what I do is pretty basic data manipulation and production of summary statistics. I don't use (and don't know) a lot of sophisticated statistical techniques, so the commands to implement them in Stata aren't included here. I do produce a fair number of graphics, and worry about how output is formatted, so this guide includes more on those topics than your average introduction to Stata.

If you find this page useful, please tell other people about it and link to it. Also, drop me a line at djiboliz@gmail.com with comments, suggestions or questions.
