The Kullback–Leibler divergence measure is used to compare the original network to its perturbation. By setting the regression coefficients to zero or non-zero values, the proposed method can remove or add arcs, making it possible to compare different network structures. The methodology is implemented with some case studies.engjournal articlehttps//doi.org/10.1016/j.eswa.2011.04.020http://www.sciencedirect.com/science/article/pii/S0957417411005367restricted access519.255Gaussian Bayesian networksConditional specificationSensitivity analysisKullback-Leibler divergence measureSensitivity-AnalysisComputer ScienceArtificial IntelligenceEngineeringElectrical & ElectronicOperations Research & ManagementEstadística matemática (Matemáticas)1209 Estadística
