[R] weighted nonlinear regression

[Antonio Olinto]

Hello,

I'm using the weighted nonlinear regression proposed in nls help.

I would like to know which is proper reference to the "Weighted version of 
Michaelis-Menten model". Which is "The White book" cited in nls help?


And, by-the-way, many thanks to Martin Maechler for this function.

Best regards,

Antonio Olinto
