Abstract

Discrete Bayesian Networks (BN’s) have been very successful as
a framework both for inference and for expressing certain causal hypotheses.
In this paper we present a class of graphical models called
the chain event graph (CEG) models, that generalises the class of
discrete BN models. It provides a flexible and expressive framework
for representing and analysing the implications of causal hypotheses,
expressed in terms of the effects of a manipulation of the generating
underlying system.We prove that, as for a BN, identifiability analyses
of causal effects can be performed through examining the topology
of the CEG graph, leading to theorems analogous to the back-door
theorem for the BN.
