getModels

When the parameter 'epmatrix' is set to TRUE, the object of class 'bnclustOmics' includes postrior probabilitis of all edges in the discovered graphs.
This function can be used to derive a consensus graph representing discovered clusters according to a specified posterior probability threshold. Only edges with posteriors above the threshold will be included
in the resulting consensus models.

Unsupervised Bayesian network-based clustering of multi-omics data. Both binary and continuous data types
are allowed as inputs. The package serves a dual purpose: it clusters (patient) samples and learns the multi-omics networks that characterize discovered
clusters. Prior network knowledge (e.g., public interaction databases) can be included via blacklisting and
penalization matrices. For clustering, the EM algorithm is employed. For structure search at the M-step,
the Bayesian approach is used. The output includes membership assignments of samples, cluster-specific MAP networks, and posterior probabilities
of all edges in the discovered networks. In addition to likelihood, AIC and BIC scores are returned. They can be used for choosing the number
of clusters.
