%description
Allows fitting of step-functions to univariate serial data where neither
the number of jumps nor their positions is known by implementing the
multiscale regression estimators SMUCE, simulataneous multiscale
changepoint estimator, (K. Frick, A. Munk and H. Sieling, 2014)
<doi:10.1111/rssb.12047> and HSMUCE, heterogeneous SMUCE, (F. Pein, H.
Sieling and A. Munk, 2017) <doi:10.1111/rssb.12202>. In addition,
confidence intervals for the change-point locations and bands for the
unknown signal can be obtained.
