 Dear colleagues,

I have used statistical software "R" in academic research, and I find very
interesting. So now I have started my studies at advanced level. I have
conducted several statistical models of the type "*nls*". In respect of
procedures for models of the type nls, I'd like you answer only one question
that I have had doubts, related to the formula "*confint*":

--- I have stated that confidence interval of the model parameters (nls)
appear related to 5% and 95. So I would like to change the value of
percentage of the confidence interval to 5% and 95%? I say this because when
I write "confint" within the environment of the software R, the results of
the confidence interval of the model parameters (nls) *always
appear*related to 2.5% and 97.5%.

Thank you very much!
