Hi everyone,

I need some help fitting a quadratic polynomial model
with NLME.

I've seen that NLME has some of the common nonlinear
models built-in, but I don't think I can use one of
these models.  These built-in models are modeling
curves with an apparent "asymptote" or more "S-shaped"
or something more complicated than what I need.  The
data I'm modeling has more of a quadratic look.

I'd greatly appreciate any comments or suggestions. 
Thank you very much in advance.
