Please consider using +the more powerful and actively developed 'drc' package. + +Functions that are fitted are the cumulative density function of the log-normal +distribution ('probit' fit), of the logistic distribution ('logit' fit), of the +Weibull distribution ('weibull' fit) and a linear-logistic model ('linlogit' +fit), 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 retrieved from a database accessed via 'odbc' +are included. As an alternative to the original fitting methods, the algorithms +from the 'drc' package can be used. + +More details can be found in the [function referenc](reference/index.html). |
