%description
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>.
