QGeNIe includes a Case Manager window that allows users to save a partial or a complete session as a case and retrieve this case at a later time. Cases are saved alongside the model, so when the model is loaded at a later time, all cases are going to be available. Case Manager window can be opened through the View Menu:
Case Manager window looks initially as follows:
Adding cases to the Case Manager
Let us add to the Case Manager the three cases analyzed in the Building a qualitative Bayesian network section of this manual. The first case involved failure of climate control on a cold day. Once the evidence in the model has been set, we click on the Add new case button (
). This results in the following dialog, which allows for entering case details.
Once we click OK, the case is visible in the Case Manager:
Adding two remaining cases to the Case Manager will result in the following window.
The Case Manager window shows the currently applied case with a grayed background.
The Show only evidence nodes button (
) reduces the number of columns displayed to those only that have any observations at all. The Apply case (
) button allows for transferring a case to the Graph View window. The Delete case button (
) removes the current case from the Case Manager. The Update applied case with network evidence (
) button transfers the current set of evidence from the current model to the current case.
