%description
Fitting regression models where, in addition to possible linear terms, one
or more covariates have segmented (i.e., broken-line or piece-wise linear)
or stepmented (i.e. piece-wise constant) effects. Multiple breakpoints for
the same variable 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>).
Segmented mixed models, i.e. random effects in the change point, are
discussed in Muggeo (2014, <doi:10.1177/1471082X13504721>). Estimation of
piecewise-constant relationships and changepoints (mean-shift models) is
discussed in Fasola et al. (2018, <doi:10.1007/s00180-017-0740-4>).
