However, when using real-world data with limited knowledge of the original dynamical system, it is challenging to determine if the learned DAG accurately reflects the underlying relationships, especially when the data come from multiple independent sources. This paper describes a methodology capable of assessing the credible interval for the existence and direction of each edge within Bayesian networks learned from data, without previous knowledge of the underlying dynamical system. It offers several advantages over classical methods, such as data fusion from multiple sources, identification of latent variables, and extraction of the most prominent edges with their respective credible interval. The method is evaluated using simulated datasets of various sizes and a real use case. Our approach was verified to achieve results comparable to the most recent studies in the field, while providing more information on the model\u2019s credibility.<\/jats:p>","DOI":"10.3390\/e26100829","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T07:19:37Z","timestamp":1727680777000},"page":"829","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Assessing Credibility in Bayesian Networks Structure Learning"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2285-3314","authenticated-orcid":false,"given":"Vitor","family":"Barth","sequence":"first","affiliation":[{"name":"Department of Electrical and Computing Engineering, University of Sao Paulo, S\u00e3o Carlos 13566-590, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3655-9933","authenticated-orcid":false,"given":"F\u00e1bio","family":"Serr\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Federal University of S\u00e3o Carlos, S\u00e3o Carlos 13565-905, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0137-6678","authenticated-orcid":false,"given":"Carlos","family":"Maciel","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, State University of S\u00e3o Paulo, Guaratinguet\u00e1 12516-410, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"key":"ref_1","unstructured":"Koller, D., and Friedman, N.
