NetworkChange (version 0.8)

Bayesian Package for Network Changepoint Analysis

Description

Network changepoint analysis for undirected network data. The package implements a hidden Markov network change point model (Park and Sohn (2020)). Functions for break number detection using the approximate marginal likelihood and WAIC are also provided.
