class RSegmented(RPackage):
    """Regression Models with Break-Points / Change-Points Estimation.

    Given a regression model, segmented 'updates' it by adding one or more
    segmented (i.e., piece-wise linear) relationships. Several variables with
    multiple breakpoints are allowed. The estimation method is discussed in
    Muggeo (2003, <doi:10.1002/sim.1545>) and illustrated in Muggeo (2008,
    <https://www.r-project.org/doc/Rnews/Rnews_2008-1.pdf>). An approach for
    hypothesis testing is presented in Muggeo (2016,
    <doi:10.1080/00949655.2016.1149855>), and interval estimation for the
    breakpoint is discussed in Muggeo (2017, <doi:10.1111/anzs.12200>)."""
