%description
Implements methods for multiple change point detection in multivariate
time series with non-stationary dynamics and cross-correlations. The
methodology is based on a model in which each component has a fluctuating
mean represented by a random walk with occasional abrupt shifts, combined
with a stationary vector autoregressive structure to capture temporal and
cross-sectional dependence. The framework is broadly applicable to
correlated multivariate sequences in which large, sudden shifts occur in
all or subsets of components and are the primary targets of interest,
whereas small, smooth fluctuations are not. Although random walks are used
as a modeling device, they provide a flexible approximation for a wide
class of slowly varying or locally smooth dynamics, enabling robust
performance beyond the strict random walk setting.
