The Sociology Statistics Reading Group is an approximately bi-weekly group to discuss interesting statistical methods papers drawn from a wide range of literatures. Each meeting we choose a paper which all members of the group read. A single discussant then walks through the material and we have a broader group discussion.

If you are at Princeton and want to join: please email our coordinator for this semester Ian Lundberg (ilundberg at princeton.edu)

Please note that the presentations below often draw figures from the original papers and sometimes from presentations graciously provided by the paper authors.
