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) chngpt: threshold regression model estimation and inference, BMC Bioinformatics, in press, DOI:10.1186/s12859-017-1863-x.

Amend, Augment and Aid Analysis of John Snow's Cholera Data
person("Peter Li", email = "lindbrook@gmail.com",
role = c("aut", "cre"))
Amends errors, augments data and aids analysis of John Snow's map
of the 1854 London cholera outbreak. The original data come from
Rusty Dodson and Waldo Tobler's 1992 digitization of Snow's map. Those
data, <http://www.ncgia.ucsb.edu/pubs/snow/snow.html>, are no longer
available. However, they are preserved in the 'HistData' package,
<https://CRAN.R-project.org/package=HistData>.
