In the mean time I have found one more way one can affect the convergence and make it smoother. I had rounding error problems with the FOCE method when fitting a PK model to log-transformed data. The run stabilized substantially when I multiplied logarithms by 10 and did the same in the control stream. As this is a transformation of both sides parameters are not affected. Best regards, Vladimir
