getGrad

object

dose

Function to return the gradient of a user defined model, see
    Examples of the fitDRModel function.

uGrad

Calculate the gradient for the non-linear part of a DRMod object. The
  gradient is used to calculate variance covariance matrix, confidence
  intervals and confidence intervals for predictions, based on a
  linearization of the non-linear model see Seber and Wild (2003) for
  details. This function is also used to calculate the design criterion
  for the <code><a href="/link/calcOptDesign?package=DoseFinding&version=0.5-5" rd-options="" data-mini-rdoc="DoseFinding::calcOptDesign">calcOptDesign</a></code> function (which depends on the
  asymptotic covariance matrix).

misc

The DoseFinding package provides functions for the design
        and analysis of dose-finding experiments (for example
        pharmaceutical Phase II clinical trials). It provides functions
        for: multiple contrast tests, fitting non-linear dose-response
        models, calculating optimal designs and an implementation of
        the MCPMod methodology.
