WebApr 1, 2024 · The most popular method is least mean square fitting, which minimizes the sum of the squares of the differences. One can also do it by formulating the normal equations and solve it as a (potentially big) linear equation system. Another approach is the Gauss-Newton algorithm, a simple iterative method to do it. It is a good exercise to … The Gauss–Newton algorithm is used to solve non-linear least squares problems, which is equivalent to minimizing a sum of squared function values. It is an extension of Newton's method for finding a minimum of a non-linear function. Since a sum of squares must be nonnegative, the algorithm can be … See more Given $${\displaystyle m}$$ functions $${\displaystyle {\textbf {r}}=(r_{1},\ldots ,r_{m})}$$ (often called residuals) of $${\displaystyle n}$$ variables Starting with an initial guess where, if r and β are See more In this example, the Gauss–Newton algorithm will be used to fit a model to some data by minimizing the sum of squares of errors between the data and model's predictions.
