 The increasing complexity of data in various fields, ranging from healthcare research to environmental science and ecology, has resulted in a need for a tool like `abn`.
 Researchers often face multivariate, tabular data where the relationships between variables are not straightforward. 
 BN analysis becomes essential when traditional statistical methods fail to analyze multivariate data with intricate relationships, as it models these relationships graphically for more straightforward data interpretation.
