Hi! I am trying to create a nonlinear model for my data at the moment using fitnlm. I have imported the data into matlab, but I am not quite sure how to define my equation. In the example in the documentation they had:
modelfun=@(b,x)b(1) + b(2)*x(:,1).^b(3)+b(4)*x(:,2).^b(5):
-> MPG ~ b1 + b2*Horsepower^b3 + b4*Weight^b5
How did they decide on this equation? Is their a certain technique?
Thank you!
