nlme random effect
Generally it is best to send questions like this to the R-SIG-Mixed-Models at R-project.org mailing list (see instructions at https://stat.ethz.ch/mailman/listinfo/r-sig-mixed-models). Many of those who read that list can reply and often much faster than I am able to.

Hello, I want build a nlme model with random effect like following formula. ?=??*exp(?), where ?? is population mean and ? is the random effect, How should I realize it? Are there any examples?
I think we would need a bit more information to be able to respond.
ps. I'm building a pharmacodynamic model and I can only find random effect in linear form. I want to try orther forms. Thanks a lot. I'm looking forward to your reply. Best Regards Lydia
