%description
Implements multiple change searching algorithms for a variety of
frequently considered parametric change-point models. In particular, it
integrates a criterion proposed by Zou, Wang and Li (2020)
<doi:10.1214/19-AOS1814> to select the number of change-points in a
data-driven fashion. Moreover, it also provides interfaces for
user-customized change-point models with one's own cost function and
parameter estimation routine. It is easy to get started with the cpss.*
set of functions by accessing their documentation pages (e.g., ?cpss).
