Hi to all,

Is there a way we can fit a non linear model to a data using non linear
least square method without necessarily initialising the parameters of the
model. I find it hard to get the initial value of the parameter. Below is a
sample of the code I have.

and cruel fate, Still I hear that gentle whisper ever pleading, God is
working, God is faithful—Only wait."*
