Overview
The medrc package is an extension to the package drc that allows you to fit hierarchical dose-response models and provides inferenc for derived parameters like the effective dose or benchmark doses. Parameters are estimated with a two-stage approach using the package metafor, or using the Lindstrom-Bates algorithm implemented in the package nlme.
