I am new to mathematica. I have 3 inputs and 1 output.I want to find a relation between input and output values. I want to find the 'N' th degree of polynomial which would approimately fit my dataset. I also tried Neural Networks but want to do Polynomial Curve Fitting or Regression.

I want to predict what degree of polynomial would fit to my data as the relation is Non-Linear(i.e. F(A)+F(B)+F(C) =Output) The values are actual weights in KG.

Kindly suggest me a method to find the 'n' degree polynomial which would approximate my data and build a relation between input and output using Mathematica 12.
