fitting with dynafit?

[ricnews]

Hi,

I'm wondering if anyone successfully used dynafit to fit their data to a
model? I tried but even with a simple test I couldn't get it to fit unless I
gave it starting values that were basically the answer. Using starting
values that converge easily in sigmaplot or excel dynafit still couldn't get
the answer.

I received no response from the author so I was hoping someone else might
use the software and be able to help me out.

Thanks,
Ric
