%description
Detect and test for changes in covariance structures of functional data,
as well as changepoint detection for multivariate data more generally.
Method for detecting non-stationarity in resting state functional Magnetic
Resonance Imaging (fMRI) scans as seen in Ramsay, K., & Chenouri, S.
(2025) <doi:10.1080/10485252.2025.2503891> is implemented in
fmri_changepoints(). Also includes depth- and rank-based implementation of
the wild binary segmentation algorithm for detecting multiple changepoints
in multivariate data.
