Compute the Bayes factor between the structures of two Bayesian networks..
Usage
BF(num, den, data, score, ..., log = TRUE)
Value
A single numeric value, the Bayes factor of the two network structures
num and den.
Arguments
num, den
two objects of class bn, corresponding to the numerator
and the denominator models in the Bayes factor.
data
a data frame containing the data to be used to compute the Bayes
factor.
score
a character string, the label of a posterior network score or
custom for the custom score. If none is specified, the default score
is the Bayesian Dirichlet equivalent score (bde) for discrete
networks and the Bayesian Gaussian score (bge) for Gaussian
networks. Other kinds of Bayesian networks are not currently supported.
...
extra tuning arguments for the posterior scores. See
score for details.
log
a boolean value. If TRUE the Bayes factor is given as
log(BF).
