Subject: Testing Nonlinear Restrictions
Dear all,
I'm interested in testing 2 nonlinear restrictions on coefficients of a nls object. Is there a package for doing this? Something in the lines of `test(nls object, res=c("res 1","res 2"),...)'
I only found the function delta.method in the alr3 library that calculates the se of a singleton nonlinear restriction of a nls object using the delta method.
Thanks in advanced for your help and suggestions.
David
