%description
Implements various procedures for finding multiple change-points from
Matteson D. et al (2013) <doi:10.1080/01621459.2013.849605>, Zhang W. et
al (2017) <doi:10.1109/ICDMW.2017.44>, Arlot S. et al (2019). Two methods
make use of dynamic programming and pruning, with no distributional
assumptions other than the existence of certain absolute moments in one
method. Hierarchical and exact search methods are included. All methods
return the set of estimated change- points as well as other summary
information.
