Asymptotic Regression Model
Hi listers,
I have some data (see attachment), and I fitted it to the Asymptotic
Regression Model with NLSstAsymptotic(xy). But I want to know the
significance of these fits. How can I accomplish this using R?
Can anyone suggest some theoretical reading on this subject?
Thanks,
Miguel
