Description: drfit provides basic functions for fitting dose-response curves to
dose-response 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). In addition, functions
checking, plotting and retrieving dose-response data of the UFT Bremen,
Department of Bioorganic Chemistry, are provided.
I would be delighted if you would join in this effort of creating useful
and useable tools for dealing with dose-response data from biological
