IIRC, DUD's provenance is old, being originally a BMDP feature.
If you want to do derivative-free nonlinear
that approximates the surface and minimizes that.

Thanks for the pointer. That seems to be an interesting
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

a) Read the Posting Guide. It will tell you things like:
1) Don't post in HTML format. Adjust your email client appropriately.
2) Don't repost. Your emails are all there, looking silly next to each other.
3) Use the search facilities yourself, such as RSiteSearch().
b) Regarding your DUD
I certainly second all Jeff's comments.
