Function with Two Independent Variables: Curve Fitting and Parameter Rejection
It is observed that two parameters (A and C) could be discarded. Based on this observation, the user could propose a new function with 3 new parameters (new A, B and C):
Y = A*X1**2+B*X2**2+C.
The graph referring to the new fitting is given below:
PS: It is more sensible to initially remove only the
parameter with the highest P(t), and redo the curve fitting, removing the next one, if P(t) > 0.05 persists! Please check this!
