%description
Detects multiple changes in slope using the CPOP dynamic programming
approach of Fearnhead, Maidstone, and Letchford (2019)
<doi:10.1080/10618600.2018.1512868>. This method finds the best continuous
piecewise linear fit to data under a criterion that measures fit to data
using the residual sum of squares, but penalizes complexity based on an L0
penalty on changes in slope. Further information regarding the use of this
package with detailed examples can be found in Fearnhead and Grose (2024)
<doi:10.18637/jss.v109.i07>.
