[R] Nonlinear regression question

2011-09-15 Thread Tatiana Donnay
Hello, If I understand good, I can't have p-value for the nls model. I have 2 vectors. And I'am doing model <- nls(crf ~a*(1-exp(-x/b)) + c, data= d, start = list(a=1, b=3, c=0)) and I want to know If my result is significat, if I can't have p-value, how can I know it? Thank y
