bnsl_p {BNSL}

Bayesian Network Structure Learning

Description

The function outputs the Bayesian network structure given a dataset based on an assumed criterion.

Usage

 bnsl_p(df, psl, tw = 0, proc = 1, s=0, n=0, ss=1)

Arguments

df

a dataframe.

psl

the list of parent sets.

tw

the upper limit of the parent set.

proc

the criterion based on which the BNSL solution is sought. proc=1,2, and 3 indicates that the structure learning is based on Jeffreys [1], MDL [2,3], and BDeu [3]

s

The value computed when obtaining the bound.

n

The number of samples.

ss

The BDeu parameter.

Value

The Bayesian network structure in the bn class of bnlearn.
