Could anyone help me? I need to use NLMIXED to do a multivariate non-linear model with one fixed and several random effects? Where would I begin? I'm just getting back into SAS after a break from college for 2 years. The code I've seen for these problems just has one random and one fixed effect. I'm trying to fit a Gompertz. Any help would be greatly appreciated.
