Dear Colleagues,
I am trying to estimate several non-linear models simultaneously. I don't
want to use non-linear mixed model, but non-linear model with same form, but
it should be estimated separately according to variable group (I have lots
of groups that have lots of observations). I would
It is not clear from your post what changes per-group. If only the
starting values change (but the data and the model structure are the
same), then you can just store the starting values you want to use for
each group in a list, and then index into this list in your call to nls.
