NettetPolynomial regression. We can also use polynomial and least squares to fit a nonlinear function. Previously, we have our functions all in linear form, that is, y = a x + b. But polynomials are functions with the following form: f ( x) = a n x n + a n − 1 x n − 1 + ⋯ + a 2 x 2 + a 1 x 1 + a 0. where a n, a n − 1, ⋯, a 2, a 1, a 0 are ... NettetUnless the closed form solution is extremely expensive to compute, it generally is the way to go when it is available. However, For most nonlinear regression problems there is no closed form solution. Even in linear regression (one of the few cases where a closed form solution is available), it may be impractical to use the formula.
