bayesvl (version 0.8.5)

bayesvl bnlearn utilities: bnlearn interface for bayesvl objects

Description

Provides the interface to the functions in the bnlearn package for network diagnostics of an object of class bayesvl.

Usage

# Interface to bn.fit function to fit the parameters of 
# a Bayesian network conditional on its structure.
bvl_bnBayes(dag, data = NULL, method = "bayes", iss = 10, ...)

# Interface to bnlearn score function to compute the score of the Bayesian network. bvl_bnScore(dag, data = NULL, ...)

# Interface to arc.strength function to measure the strength of the probabilistic # relationships expressed by the arcs of a Bayesian network. bvl_bnStrength(dag, data = NULL, criterion = "x2", ...)

# Interface to bn.fit.barchart function to plot fit # the parameters of a Bayesian network conditional on its structure. bvl_bnBarchart(dag, data = NULL, method = "bayes", iss = 10, ...)

Arguments

dag

an object of class bayesvl

data

a data frame containing the variables in the model.

method

a character string, either mle for Maximum Likelihood parameter estimation or bayes for Bayesian parameter estimation (currently implemented only for discrete data).

iss

a numeric value, the imaginary sample size used by the bayes method to estimate the conditional probability tables associated with discrete nodes

criterion

a character string, the method using for measuring

...

extra arguments from the generic method

Value

bvl_bnScore() return a number, value of score.
