Hi there,

I have a set of data points

{(X1,Y1), (X2,Y2),........(Xn,Yn)}

I would like to approximate the relation between X and Y as a parabola. Assuming the parabola has form y = Ax^2+Bx+C, can somebody please provide me with the least squares regression formulas for A, B and C.

Any help is greatly appreciated.

Thanks,

AP
