Sensitivity analysis of Bayesian networks to parameters of the conditional probability model using a Beta regression approach

作者:

Highlights:

• Global sensitivity analysis for BBN addressed with the viewpoint of beta regression.

• Applicable to any types of BBN (discrete, Gaussian, hybrid).

• Contributions are graphically depicted by the partial effects on the beta mean.

• Confidence measured by the evolution of the beta σ parameter.

• Combination with gradient boosting and stability analysis enhances the screening.
