gera.bn.structure: Learn the Bayesian Network structure from data and build a PA model

Description

This function receives a data set, a list of parameters to learn the BN structure based on this data set. Then with the BN ready it will build a PA model if required. The process will then save the graphs of BN and PA and PA parameters.

Usage

gera.bn.structure(data.to.work, white.list = "", black.list = "",
  nreplicates = 1000, cb.algorithms = c("gs", "iamb", "fast.iamb",
  "inter.iamb", "mmpc", "si.hiton.pc"), sb.algorithms = c("hc", "tabu"),
  cb.tests = "", sb.tests = "", optimized.option = "FALSE",
  outcome.var, build.pa)

Arguments

data.to.work

is a data from which the BN structure will be learned.

white.list

is a list of mandatory connections of BN structure to be created.

black.list

is a list of forbiden connections of BN structure to be created.

nreplicates

is how many times the boostrap will run.

cb.algorithms

the name of constrained-based algorithms.

sb.algorithms

the name of score-based algorithms.

cb.tests

the name of tests for constrained-based algorithms.

sb.tests

the name of network scores for score-based algorithms.

optimized.option

a paremeter of bnlearn package to optmize the BN learn structre learning.

outcome.var

is the outcome (dependent) variable.

build.pa

indicates if the process will bulld a PA model or not.
