Jorn,
As the matter of fact, you can use any reasonable error model.
Particularly, you can assume the additive (not proportional!)
error variance to be concentration-dependent,
e.g., a stepwise function.
However, I am not sure that the bias can be
eliminated by making the residual error model
more complex. Modifying your structural
model might be more logical.
Best regards,
Vladimir
