In order to account for the data, we introduce an additional layer of observable variables (observables, O)inanobvious way: each effect node e ∈ E has an edge pointing to a unique ... 0, each marginal node can be assigned to all suitable core nodes. As a consequence, there is always a best scoring topology with an empty core graph. ν makes signalling to the m...
