Description:
A somewhat outdated package of basic and easy-to-use functions forfitting dose-response curves to continuous dose-response data calculating sometoxicological parameters and plotting the results. Please consider usingthe more powerful and actively developed drc package. Functions that arefitted are the cumulative density function of the log-normal distributionprobit fit of the logistic distribution logit fit of the Weibulldistribution weibull fit and a linear-logistic model linlogit fitderived from the latter which is used to describe data showing stimulation atlow doses hormesis. In addition functions checking plotting and retrievingdose-response data retrieved from a database accessed via odbc are included.As an alternative to the original fitting methods the algorithms from the drcpackage can be used.
