Leonid,
I think W is correctly specified in Jing's control stream below. As she has
coded it, W is the residual standard deviation (given the ETAs) for the
combined proportional and additive error model. That is,
Var(Y | ETAs) = (W2)Var(ERR(1)) = W2 = THETA(8)**2 + (THETA(9)**2)*F*F
where THETA(8) is the residual SD for the additive component and THETA(9) is
the residual CV for the proportional component.
