Thank you for your answers !!
I was thinking about some multidimensional linear approximation, where
the basis you use is ( for points of coordinates (x_i, y_i ) ) the
vectors
The family of x_i, x_i
The family of x_i, x_i^2
The family of x_i, x_i^3
The family of x_i, x_i^4
...
But it turns out S

Are you speaking about the Taylor expansion ?
If so, it is impl
