Hi,
This problem was discussed before on NMUSERS, here's a link with code
suggested by Leonid Gibiansky and Mats Karlsson (code allowing for a
combined - additive and proportional error in log space):

You model the log transformed
Hi Katrin,
You'll have to take the natural logarithm of your DVs
I would change your error block to:
$ERROR
IPRED=LOG(F+1E-16) ; Protection against LOG(0) in case of dosing events etc
Y=IPRED+ERR(1) ; FOR PROPORTIAL ERROR
Cheers!
