DUD (Does not Use Derivatives) for nonlinear regression in R?
Hi, All SAS has DUD (Does not Use Derivatives)/Secant Method for nonlinear regression, does R offer this option for nonlinear regression? I have read the helpfile for nls() and could not find such option, any suggestion? Thanks, Derek [[alternative HTML version deleted]]
Is DUD available in nls()?
