Use Math.NET's Fit.Polynomial method on functions of multiple parameters

I previously used Math.NET Numerics library's Fit.Polynomial method to fit a cubic polynomial on a set of data that could be modeled as a function of one parameter y=f(x).
Now I would like to similarly find a 2 or 3 order polynomial that fits data that could be modeled as a function depending on multiple parameters y=f(x1, x2, x3, x4).

Is there already a built-in function in Math.NET that can compute that polynomial?
If not, do you see how I could manipulate my data in order to submit it to Fit.Polynomial?

Notice that the x in the linear model can also be a vector x=[x1 x2 ⋯ xk] and the arbitrary functions fi(x) can accept vectors instead of scalars.
Here is something nearly about what you want.
