Assessment Sensitivity Analysis

Parameter Sensitivity Analysis

This function allows you, by means of sampling, to compute the impact of the uncertainty of the "parameter" nodes with regard to the target nodes. By default, the parameter nodes are root nodes (i.e. the nodes without parent), the target nodes are leaf nodes (i.e. the nodes without child).

The result of this simulation can be saved in a file. The result of the analysis is presented with a curve that represents the repartition function of the probabilities of each state, plus a bar chart representing the probability density function. In addition to these graphical results, the mean and the standard deviation of the probabilities of the target states are also given. The mean corresponds to the marginal probability displayed in the monitors.

The analysis can be performed over all nodes or over a subset of selected nodes. Translucent nodes are not taken into account in this analysis. If applicable, the evidence context is taken into account and shown under the graphs.

The contextual menu allows you to display node comments instead of node names as well as the long names of states. You can also copy the chart as a graphic.
