I have a parameter (let's call it power) with x y coordinates. Now I need to do a 4th order polynomial fit for power, with x and y, equation should includes below terms:
x, y, x^2, x*y, y^2, x^3, x^2*y, x*y^2, y^3, x^4, x^3*y, x^2*y^2, x*y^3, y^4
Is there a function in SAS doing this? I saw some examples about doing polynomial prediction in SAS online, but they usually only fit y = f(x).
