The package bnmonitor
can be installed from CRAN using the command
install.packages("bnmonitor")
and loaded in R with
library(bnmonitor)
#> Warning: package 'bnmonitor' was built under R version 4.3.3
Note that bnmonitor
requires the package gRain
which, while on CRAN,
depends on packages that are on Bioconductor both directly and through
the gRbase
package, which depends on RBGL
:
install.packages("BiocManager")
BiocManager::install(c("graph", "Rgraphviz", "RBGL"))
install.packages("gRain")
bnmonitor
provides a suite of function to investigate either a
data-learnt or an expert elicited BN. Its functions can be classified
into the following main areas:
Parametric sensitivity analysis: Investigate the effect of changes in some of the parameter values in a Bayesian network and quantify the difference between the original and perturbed Bayesian networks using dissimilarity measures (both for discrete and Gaussian BNs).
Robustness to data: Verify how well a Bayesian network fits a specific dataset that was used either for learning or for testing (only for discrete BNs).
Node influence: Quantify how much the nodes of a Bayesian network influence an output node of interest (only for discrete BNs).
Edge strength: Assess the strength of the edges of a Bayesian network (only for discrete BNs).
Other investigations: Including the diameter of the conditional probability tables, measures of asymmetric independence, and level amalgamation.
Refer to the articles section for case studies showcasing the use of the
bnmonitor
functions.
