Ned,
It looks like Mathematica already can do this:
In[673]:=
data = Table[{y = RandomComplex[],
RandomReal[{0.9, 1.1}] y^2 + RandomReal[{0.9, 1.1}] y + 1 +
I}, {20}];
In[672]:= Fit[data, {1, x, x^2}, x]
Out[672]= (0.988738 +
0.984148 I) + (1.0509 - 0.0357287 I) x + (1.0156 + 0.0497595 I) x^2
Cheers -- Sjoerd
