CptNonPar (version 0.3.2)

CptNonPar-package: CptNonPar: Nonparametric Change Point Detection for Multivariate Time Series

Description

Implements the nonparametric moving sum procedure for detecting changes in the joint characteristic function (NP-MOJO) for multiple change point detection in multivariate time series. See McGonigle, E. T., Cho, H. (2025) tools:::Rd_expr_doi("10.1093/biomet/asaf024") for description of the NP-MOJO methodology.
