  In a recent paper published in the Journal of Causal Inference, Philip Dawid
has described a graphical causal model based on decision diagrams. This article
describes how single-world intervention graphs (SWIGs) relate to these
diagrams. In this way, a correspondence is established between Dawid's approach
and those based on potential outcomes such as Robins' Finest Fully Randomized
Causally Interpreted Structured Tree Graphs. In more detail, a reformulation of
Dawid's theory is given that is essentially equivalent to his proposal and
isomorphic to SWIGs.
