Asunto: Re: [R] nls problem with R
The fact that T2 and V2 are of different lengths seems like a
likely culprit. Other than
Thanks Ruben.
Your suggestion about more deeper analysis about the model itself is really

I am trying out some new initial values based on the analysis of the special

Thanks Andrew.
I am sorry for some typos that I omit some numbers of T2.
Based on your suggestion,I think the problem is in the initial values.
And I will read more theory about the non-linear regression.
