MoTBFs (version 2.0)

goodnessMoTBFBN: BIC of a hybrid BN

Description

Compute the BIC score and the loglikelihood from the fitted MoTBFs functions in a hybrid Bayesian network, i.e., from objects of class motbf.fit.

Usage

logLikelihood.MoTBFBN(object, data)
BiC.MoTBFBN(object, data)

Value

A numeric value giving the log-likelihood of the BN.

Arguments

object

The output of the 'motbf.fit()' function

data

The dataset of class data.frame.
