%description
Analyze functional data and its change points. Includes functionality to
store and process data, summarize and validate assumptions, characterize
and perform inference of change points, and provide visualizations. Data
is stored as discretely collected observations without requiring the
selection of basis functions. For more details see chapter 8 of Horvath
and Rice (2024) <doi:10.1007/978-3-031-51609-2>. Additional papers are
forthcoming. Focused works are also included in the documentation of
corresponding functions.
