Data Modelling with Additive Bayesian Networks

Description

Additive Bayesian network models are equivalent to multivariate regression using graphical modelling. This library provides routines to help determine optimal Bayesian network models for a given data set, where these models are used to identify statistical dependencies in messy, complex data. The additive formulation of these models is equivalent to multivariate generalised linear modelling (including mixed models). The usual term to describe this model selection process is structure discovery. The core functionality is concerned with model selection - determining the most robust empirical model of data from interdependent variables. A comprehensive set of documented case studies, numerical accuracy/quality assurance exercises, and additional documentation are available from the abn website.
