Abstract

In this talk, I will introduce a class of discrete statistical models to represent context-specific conditional independence relations for discrete data. These models can also be represented by sequences of context-DAGs (directed acyclic graphs). We prove that two of these models are statistically equivalent if and only their contexts are equal and the context DAGs have the same skeleton and v-structures. This is a generalization of the Verma and Pearl criterion for equivalence for DAGs. This is joint work with Liam Solus. A video abstract is available at https://youtu.be/CccVNRFmR1I .
