[R] statistical significance, nonlinear regression

2008-12-24 Thread adam99
I am using nonlinear regression to fit a couple of variables to a set of measurements. I would like to do some significance tests for the estimated parameters. I am able to check the confidence intervals using the Jacobian coming out of nonlinear regression. I do see in a paper which shows

See ?confint2 in the nlrwr package for confidence intervals and for more info on hypothesis testing in nonlinear regression focused on R see the book associated with that package. On Wed, Dec 24, 2008 at 6:20 PM, adam99 adamquest...@gmail.com wrote: I am using nonlinear regression to fit a
