Class "Combined1"

Description

The class Combined1 defines the the residual error variance according to the formula g(sigmaInter, sigmaSlope, cError, f(x, theta)) = sigmaInter + sigmaSlope*f(x,theta)). The class Combined1 inherits from the class ModelError.

Objects from the class

Combined1 objects are typically created by calls to Combined1 and contain the following slots that are inherited from the class ModelError:

outcome:: A string giving the name of the outcome.
equation:: An symbolic expression of the model error.
derivatives:: A list containing the derivatives of the model error expression.
sigmaInter:: A numeric value giving the sigma inter of the error model.
sigmaSlope:: A numeric value giving the sigma slope of the error model.
cError:: A numeric value giving the exponant c of the error model.
