Bayesian information criterion

(1.2 hours to learn)


The Bayesian information criterion (BIC) is a rough approximation to the marginal likelihood, based on the asymptotic behavior of the Laplace approximation as more data is observed.


This concept has the prerequisites:


  • Know the formula for the BIC
  • Derive the formula in terms of the Laplace approximation
