Factorization criteria for Markov models induced by directed acyclic graphs via marginalization
- Thomas Richardson (University of Washington, USA)
Abstract
We will give a characterization of the distributions with Markovian structure corresponding to directed acyclic graphs under marginalization. These Markov models correspond to graphs containing directed and bi-directed edges, but no directed cycles, also called, acyclic directed mixed graphs. This factorization criterion leads directly to a parameterization in the binary case.
