Likelihood functions for the studied BNs are formulated, methods for their maximization are described and, finally, the results of a study concerning the reliability of revealing BNs' roles are reported. The results of BN node assignments can be applied to problems of the analysis of gene expression profiles.}, type={artykuł}, title={Node assignment problem in Bayesian networks}, keywords={biostatistics, Bayesian networks, maximum likelihood, confidence intervals}, }
