Figure 3.

Plate models for Scenario 2 of Example 2; that is, for the burglary-alarm-call scenario where there is a single random variable $\mathsf{calls}$. Left: A partial plate model (without the $\mathsf{calls}$ random variable), indicating that parameterized random variables $\mathsf{burglary}(x)$ and $\mathsf{alarm}(x)$ must be replicated for each person x; the domain consists of the set of persons as marked in the top of the plate. Note that each parameterized random variable must be associated with probabilistic assessments; in this case, the relevant ones from Figure 1. Right: A plate model that extends the one on the left by including the random variable $\mathsf{calls}$.
