WebJul 11, 2024 · This paper proposes a hybrid Bayesian Network (BN) method for short-term forecasting of crude oil prices. The method performed is a hybrid, based on both the aspects of classification of influencing factors as well as the regression of the out-of-sample values. For the sake of performance comparison, several other hybrid methods have also been … WebCreating Bayesian network structures. The graph structure of a Bayesian network is stored in an object of class bn (documented here ). We can create such an object in various ways through three possible representations: the arc set of the graph, its adjacency matrix or a model formula . In addition, we can also generate empty and random network ...
