%description
Implementations of MOSUM-based statistical procedures and algorithms for
detecting multiple changes in the mean. This comprises the MOSUM procedure
for estimating multiple mean changes from Eichinger and Kirch (2018)
<doi:10.3150/16-BEJ887> and the multiscale algorithmic extension from Cho
and Kirch (2022) <doi:10.1007/s10463-021-00811-5>, as well as the
bootstrap procedure for generating confidence intervals about the
locations of change points as proposed in Cho and Kirch (2022)
<doi:10.1016/j.csda.2022.107552>. See also Meier, Kirch and Cho (2021)
<doi:10.18637/jss.v097.i08> which accompanies the R package.
