%description
Threshold regression models are also called two-phase regression,
broken-stick regression, split-point regression, structural change models,
and regression kink models, with and without interaction terms. Methods
for both continuous and discontinuous threshold models are included, but
the support for the former is much greater. This package is described in
Fong, Huang, Gilbert and Permar (2017) <DOI:10.1186/s12859-017-1863-x> and
the package vignette.
