Lab assignments

Getting Started

Our course uses the Stata statistical package. You can purchase Stata for your personal computer (most Economics majors do this) or you may use it for free at computer clusters around the university.

Computer Labs

Each week we shall have a computer lab to explore different methods of data analysis.  The links below go to each lab.

Advice for being efficient in labs:  

The first time you use a generic data analysis tool (e.g., a histogram or regression), the lab instructions will include the relevant Stata commands for using that tool.  Subsequent labs will use data analysis tools from previous labs, but instructions will not be repeated.  I recommend that you maintain a list of Stata commands for each analysis, adding to it after each lab that you complete.  That way, you have a handy reference sheet available, which will save you time when doing the labs or projects for other classes.
