Guidelines for working together on homework:
1) You have to clearly state, at the top of the homework, right under your own name, who you worked with.
2) Each student must answer each question in their own words. That is, the homework you turn in has to represent your answers and your interpretation of the results. Each student must turn in homework that is original to them.
3) Working together means you can check your answers with your colleagues, and you are encouraged to share information about how to get Stata to perform certain operations. You are expected to run your own Stata commands, and create your own logs.
