Explaining Bayesian networks

The value distal for node Location is very likely (P = 0.981).

We were able to construct five arguments based on the evidence that should be the effect of the value distal for node Location (L).
The arguments are ordered by how influential they are for the value of the node Location (L).

• Argument 1: Node Biospy has value adeno

• Argument 2: Node Gastro-location has value distal

• Argument 3: Node Endosono-mediast has value no

Node Bronchoscopy has value no

Node Lapa-diagragm has value no

Node CT-organs has value none

Node X-fistula has value no

• Argument 4: Node Endosono-truncus has value non-determ

Node Lapa-truncus has value yes

Node CT-truncus has value yes

• Argument 5: Node Sono-cervix has value no

Node Physical-exam has value no

The value scirrheus of node Shape is certain (P = 1.00).

We were able to construct four arguments based on the evidence that should be the effect of the value scirrheus for node Shape (S).
