The Class "Proportional" defines the the residual error variance according
to the formula g(sigma_inter, sigma_slope, c_error, f(x, theta)) = sigma_slope*f(x,theta).
Arguments
Objects from the Class Proportional
Objects are typically created by calls to Proportional and contain the following slots
that are inherited from the class Combined1:
Slots for the <code>Proportional</code> objects
.Object:
An object of the Class Proportional
sigma_inter:
A numeric value giving the sigma inter of the error model
sigma_slope:
A numeric value giving the sigma slope of the error model
