bn
S3 class.bn
is a list containing at least the
following components:
learning
: a list containing some information about
the results of the learning algorithm. It's never changed
afterward.whitelist
: a sanitized copy of thewhitelist
parameter (a two-column matrix, whose columns are labeledfrom
andto
).blacklist
: a sanitized copy of theblacklist
parameter (a two-column matrix, whose columns are labeledfrom
andto
).test
: the label of the conditional independence test
used by the learning algorithm (a character string). The
label of the network score is used for score-based and hybrid
algorithms, and "none" for randomly generated graphs.ntests
: the number of conditional independence tests
or score comparisons used in the learning (an integer value).algo
: the label of the learning algorithm or the
random generation algorithm used to generate the network
(a character string).args
: a list. The values of the parameters of
either the conditional tests or the scores used in the learning
process. Only the relevant ones are stored, so this may be
an empty list.alpha
: the target nominal type I error rate (a
numeric value) of the conditional independence tests.iss
: a positive numeric value, the imaginary
sample size used by thebge
andbde
scores.phi
: a character string, eitherheckerman
orbottcher
; used by thebge
score.k
: a positive numeric value, the penalty per
parameter used by theaic
,aic-g
,bic
andbic-g
scores.prob
: the probability of each arc to be present in
a graph generated by theordered
graph generation algorithm.burn.in
: the number of iterations for theic-dag
graph generation algorithm to converge to a stationary (and uniform)
probability distribution.max.degree
: the maximum degree for any node in a graph
generated by theic-dag
graph generation algorithm.max.in.degree
: the maximum in-degree for any node in
a graph generated by theic-dag
graph generation algorithm.max.out.degree
: the maximum out-degree for any node in
a graph generated by theic-dag
graph generation algorithm.training
: a character string, the label of the training
node in a Bayesian network classifier.nodes
: a list. Each element is named after a node
and contains the following elements:mb
: the Markov blanket of the node (a vector of
character strings).nbr
: the neighbourhood of the node (a vector of
character strings).parents
: the parents of the node (a vector of
character strings).children
: the children of the node (a vector of
character strings).arcs
: the arcs of the Bayesian network (a two-column
matrix, whose columns are labeledfrom
andto
).
Undirected arcs are stored as two directed arcs with opposite
directions between the corresponding incident nodes. Additional (optional) components under learning
:
optimized
: whether additional optimizations have been used in
the learning algorithm (a boolean value).restrict
: the label of the constraint-based algorithm used in
thertest
: the label of the conditional independence test used in
themaximize
: the label of the score-based algorithm used in themaxscore
: the label of the network score used in the
