EdPolicyWorks Speaker Series: Tracy Sweet

Latent Variable Network Models: How can they be used for Education Research?

  • - EST
  • Holloway Hall (Bavaro Hall 116)


Social network analysis focuses on the relationships among individuals in systems such as schools, and social network models are used to determine the effects of individual attributes on these relationships. Because of  the ill-defined dependence structure among network ties, one class of network models uses latent variables. Latent variable network models are also relatively simple to fit, allowing for a number of interesting extensions. In this talk, I will present two examples from my own research: a multilevel model mediation model and a latent variable model for social influence as well as discuss some future directions.
