Provides tools for assessing the shape of a dose-response
curve by testing linearity and non-linearity at user-defined cut-offs. It
also provides two methods of estimating a threshold dose, or the dose at
which the dose-response function transitions to significantly increasing:
bi-linear (based on pkg 'segmented') and smoothed with splines (based on
pkg 'mgcv').
