In conclusion, remember that this phase needs you to critically assess what is going on and decide if a network makes sense or not. In this case, without any further input, let us assume it does.
Training the Network
Training the network means calculating the conditional probabilities that are encoded into the links. This is just a calculation of an empirical probabilities based on the data, even though we have modified the network in the previous step. Bear this in mind when looking at the results. There is not much to be said about this step in terms of actually using the tool.
Evaluating a Scenario
Now that the model is complete and trained, we can finally use it to evaluate a scenario. How mentioned before, let us consider a very simple question.
