Webb20 okt. 2024 · Polynomials cannot fit logarithmic-looking relationships, e.g., ones that get progressively flatter over a long interval Polynomials can't have a very rapid turn These are reasons that regression splines are so popular, i.e., segmented polynomials tend to work better than unsegmented polynomials. Webb20 maj 2013 · So, like Wayne said, you need to decide on an order. As the orders get higher, the fit will get better, but the worse the oscillations in between your training points will be. Once you know that, just do Theme Copy coefficients = polyfit (x, y, theOrder); % x is the year. x = 2000; estimatedY = polyval (coefficients, x); 11 Comments
