Overview

About

Maintained by Sheila GoerzFirst published 2026-01-063 releasesCRAN page ↗

Provides methods to detect structural changes in time series or random fields (spatial data). Focus is on the detection of abrupt changes or trends in independent data, but the package also provides a function to de-correlate data with dependence. The functions are based on the test suggested in Schmidt (2024) DOI:10.3150/23-BEJ1686 and the work in Görz and Fried (2025) DOI:10.48550/arXiv.2512.11599.
