R help - Oct 2007 - constructing a self-starting non-linear model

Dear all,
 
I am trying to define a selfStart function for a non-linear model, which is a
log-transformed SSmicmen model with multiplicative errors and so it is required
to make them additive:
 
log(y)=log(a)+log(x)-log(1+x/b)
 
 
Any ideas about how to use the "peeling" method to derive the
"initial" argument and get the initial values?
 
Thank you for being always there!:)

Does it not work just to reuse the SSmicmen initializer?
