I'm trying to compute the standar error of a non-linear regression fit, I find the answer in this post

Non-linear regression confidence interval

But i did't find that formula in any other place,and I just can't do my homework using a formula without any source or proof. Could you please help me?

  • $\begingroup$ Have you tried googling for "non-linear least squares" analysis? There are many stats references on line. math.gmu.edu/~igriva/book/Appendix%20D.pdf page 754. $\endgroup$
