What Should I Do Before Class Begins?

In addition to exploring what’s available on this website, you should …

  1. Buy the book. During the course, we will read Paul Rosenbaum’s book Causal Inference, which is available as an e-book or in paperback for under $15. Please buy the book and get started reading it as soon as you can.

  2. Once you have registered for the course, please visit our Welcome to 500 survey. You’ll need to log into Google via CWRU to access the survey, which should take about 10 minutes to complete. Please complete the survey as soon as possible.

  3. Download the software. Install R and RStudio and some necessary R packages on a computer you can control throughout the semester. Details are available here.
