Thanks, Maarten (also for the link you sent me on the subsequent e-mail!)
I want to explore non-linear relationships between outcomes that have so far
been analyzed as if their relationship was linear. For this, I need to learn
some statistical techniques to explore these relationships (besides normal
regression, or even generalized estimation equations), if I am not wrong.
This is more difficult to find in normal courses, at least the ones I have
been finding, as they focus on linear relationships between variables...

I only gave examples from my own discipline. It may be more helpful for you
to look for summer courses centered around medical/biostat fields. The
statistics is of course the same, but terminology tends to differ a lot from
discipline to discipline. Since you will most likely be communicating within
your own discipline, it pays to start learning within your own field. Later
you can diversify to other disciplines.

That depends on what you mean with non-linear: is it non-linear in the
variables or in the parameters. Often people tend to equate this with a
particular estimator, e.g. non-linear least squares, maximum likelihood, or
generalized method of moments. So you need to specify more precisely what
you mean with that.

Hope this helps,
