Package: PCBN 0.1.1

PCBN: Inference of Pair-Copula Bayesian Networks

Creates, fits and samples Pair-Copula Bayesian Networks (PCBN) under some restrictions on the underlying Directed Acyclic Graph (DAG), that is, no active cycles nor interfering v-structures, following Derumigny, Horsman and Kurowicka (2025) <doi:10.48550/arXiv.2510.03518>.
