The primary (if not the only) documentation for the 'nlme'
function, beyond that in the 'nlme' package, is Pinheiro and Bates.
Your example is not self contained, which makes it not feasible
for me to say much about your problem. Have you tried to reduce the
size and complexity
Hello. I am trying to fit a nonlinear mixed model involving 3 parameters.
I have successfully made a self-starting function. getInitial() correctly
outputs the initial estimates. I can also use the nlsList with this
function to get the separate nonlinear fits by group. However, I get an
error
