[R-pkgs] gRaven package - Bayes Nets: 'RHugin' Emulation with 'gRain'
Dear all, I am pleased to announce that CRAN now hosts my package gRaven. This provides wrappers for functions in the 'gRain' package to emulate some 'RHugin' functionality, allowing the building of Bayesian networks consisting of discrete chance nodes incrementally - through adding nodes, edges and conditional probability tables, the setting of evidence, whether 'hard' (boolean) or 'soft' (likelihoods), and querying marginal joint probabilities and normalizing constants. Computations will typically not be so fast as they are with 'RHugin', but this package should assist users without access to the commercial package 'Hugin' to use existing code written to use 'RHugin'. I am open to extending the functionality of the package in future, in response to user demand. regards, Peter Green -- Peter Green, p.j.green at bristol.ac.uk -- Emeritus Professor of Statistics & Professorial Research Fellow University of Bristol, Bristol BS8 1UG, UK T: +44 117 455 2611; W: https://petergreenweb.wordpress.com/
