  (with Possibly Random Effects)'

abstract: 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, <https://doi.org/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, <https://doi.org/10.1080/00949655.2016.1149855>),
  and interval estimation for the breakpoint is discussed in Muggeo (2017, <https://doi.org/10.1111/anzs.12200>).
  Segmented mixed models, i.e. random effects in the change point, are discussed in
  Muggeo (2014, <https://doi.org/10.1177/1471082X13504721>). Estimation of piecewise-constant
  relationships and changepoints (mean-shift models) is discussed in Fasola et al.
  (2018, <https://doi.org/10.1007/s00180-017-0740-4>).
