In tavazzie/bnstructScore: Bayesian Network Structure Learning from Data with Missing Values

bnstruct

R package for Bayesian Network Structure Learning from Data with Missing Values

Introduction

Bayesian Networks are a powerful tool for probabilistic inference among a set of variables, modeled using a directed acyclic graph. However, one often does not have the network, but only a set of observations, and wants to reconstruct the network that generated the data. The bnstruct package provides objects and methods for learning the structure and parameters of the network in various situations, such as in presence of missing data, for which it is possible to perform imputation (guessing the missing values, by looking at the data). The package also contains methods for learning using the Bootstrap technique. Finally, bnstruct, has a set of additional tools to use Bayesian Networks, such as methods to perform inference and interventions.

In particular, the absence of some observations in the dataset is a very common situation in real-life applications such as biology or medicine, but very few software around is devoted to address these problems. bnstruct is developed mainly with the purpose of filling this void.

Installation

The latest stable version of bnstruct is available on CRAN and can be installed with ```{r eval=FALSE} install.packages("bnstruct")

from within an R session.

The latest development version of `bnstruct` can be found on GitHub
[here](https://github.com/sambofra/bnstruct).

In order to install the package, it suffices to launch
`R CMD INSTALL path/to/bnstruct`
from a terminal, or `make install` from within the package source folder.

Being hosted on GitHub, it is also possible to use the `install_github`
tool from an R session:

```{r eval=FALSE}
library("devtools")
install_github("sambofra/bnstruct")

For Windows platforms, a binary executable of the latest stable version is available on CRAN.

bnstruct requires R >= 3.5, and depends on bitops, igraph, graph and methods. Package Rgraphviz is requested in order to plot graphs, but is not mandatory.
