Vergleich verschiedener Analysenmethoden,ence consists of updating the probability distributions of the variables according to the newly available evidence. For example, we need to calculate the conditional distribution of each element of a set of variables of interest (e.g., diseases) given the evidence (e.g., symptoms).

Graphically Specified Models,s of independence assumptions. However, these models are ad hoc because they are suitable only for the diseases-symptoms paradigms. In this chapter we show how more general dependency models are obtained using graphs. The basic idea consists of using undirected or directed graphs to build a dependency model.
