BNs encode conditional probability statements, where the arrows are missing

BNs can be used to forecast risk

We check the forecasts that flow from the model starting with the largest structure and moving on to the smallest elements of the structure.

Which model is the best fit overall?

Which of the individual nodes are poorly modelled?

What is the z-score for forecasts that flow from the model given the setting of the parent nodes?
