I'm quite new to proc nlmixed, but I think that it might be appropriate and very useful for a certain nonlinear regression problem.
I have received parameter estimates that seem reasonable. I have included one random (normally distributed) variable in my non-linear function. Now, I'd like to get an estimate of the function with a confidence interval. I've tried the predict statement, but it seems that it yields results that does not follow the function I modeled in the first place.
When I try to use the estimate statement, I get the following Error note in the Log:
"ESTIMATE statement expressions are not allowed to depend on random effects." But why is the proc then called Mixed???
