DIdata


A .csv file containing a dose column "Dose", a column "n" defining how many cases received that dose,
and an outcome column "Tumor" indicating how many of cases of the outcome were observed at the dose level.

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').
