    Nonlinear mixed model

    I would like to better understand nonlinear mixed effects models and how to use them. The application I am working on is a Gompertz type non-linear Mixed Model. The equation goes something like Yit=(Ym +mui)exp(-exp(b(t-t')))+eit. With i for the individual and t for the time of the measurement (fixed effect.)

    mui is the random deviations term. If I have say 4 variables for my random effects, what would my equation look like?
