Thanks very much Douglas for the pointer to nlm.
Maybe the "Notes on R" maintainer can add at least a mention of nlm in the
section on nonlinear fitting?
I never did nonlinear fitting in S-Plus before, so I have nothing to
unlearn, but I was hoping someone could show me how to do a least squares
fit with nlm.
Please show me how to fit the model
y=a*x^b + c
by least squares. I would like parameter estimates plus the standard
error for each param.
(This example could replace the current nonlinear fitting section in
"Notes on R")
Thanks very much for any help!
