HDcpDetect - Detect Change Points in Means of High Dimensional Data
Objective: Implement new methods for detecting change
points in high-dimensional time series data. These new methods
can be applied to non-Gaussian data, account for spatial and
temporal dependence, and detect a wide variety of change-point
configurations, including changes near the boundary and changes
in close proximity. Additionally, this package helps address
the “small n, large p” problem, which occurs in many research
contexts. This problem arises when a dataset contains changes
that are visually evident but do not rise to the level of
statistical significance due to the small number of
observations and large number of parameters. The problem is
overcome by treating the dimensions as a whole and scaling the
test statistics only by its standard deviation, rather than
scaling each dimension individually. Due to the computational
complexity of the functions, the package runs best on datasets
with a relatively large number of attributes but no more than a
few hundred observations.
