qss.student allows students to unpack and complete problem sets from

K. Imai (2017) Quantitative Social Science: An Introduction. Princeton University Press.

or one of the supplementary sets available from the author.


The problem sets are a bit too big for CRAN, so you’ll want to make sure you’ve got the devtools package installed and then grab the package from GitHub. Like this:



  • This package contains all the questions, all the data, but none of the answers!
  • It is a complement to the qss package. That package contains the code from the book chapters. This one has the problems that appear after each chapter.
