## Abstract

The preceding chapters have described an approach to assessment design and analysis that exploits the advantages of Bayesian networks. This chapter addresses the problem of estimating these distributions or parameters they are modeled in terms of. It lays out a general Bayesian framework for expressing educational measurement models in these terms. It then describes and illustrates two estimation approaches: Bayes modal estimation via the expectation–maximization (EM) algorithm and Markov Chain Monte Carlo (MCMC) estimation.
