Title: Dose-response data evaluation
Author: Johannes Ranke <jranke@uni-bremen.de>
Maintainer: Johannes Ranke <jranke@uni-bremen.de>
Depends: R,stats,RODBC
Description: drfit provides basic functions for accessing the
dose-response data of the UFT Bremen, Department of Bioorganic Chemistry,
fitting dose-response curves to this and similar data, calculating some
(eco)toxicological parameters and plotting the results. Functions that are
fitted are the cumulative densitiy function of the lognormal distribution,
of the logistic distribution and a linear-logistic model, derived from the
latter, which is used to describe data showing stimulation at low doses
(hormesis). The author would be delighted if anyone would join in this
effort of creating useful and useable tools for dealing with dose-response
data from biological testing.
