Iterative Conditional Fitting for Gaussian Ancestral Graph Models
Iterative Conditional Fitting Gaussian Ancestral Graph Models
2012/9/19
Ancestral graph models, introduced by Richard-son and Spirtes (2002), generalize both Markov random fields and Bayesian networks to a class of graphs with a global Markov property that is closed under...

We introduce a new method for estimating the parameters of exponential random graph models. The method is based on a large-deviations approximation to the normalizing constant shown to be consistent u...
