Hi Mark,

Not sure about this but how about estimating THETAS scaling fix OMEGAs (e.g.=
 CL = THETA(1)*EXP(THETA(2)*ETA(1)) ; $OMEGA 1 fix)? Then you can implemen=
t the prior in the same way for random effect parameters as you do for fixed=
 effect parameters.

Ps. Probably not be compatible with MU-parameterization.

Best regards,
