A mathematical procedure for finding the best-fitting curve to a given set of points by minimizing the sum of the squares of the offsets ("the residuals") of the points from the curve. The sum of the squares of the offsets is used instead of the offset a

引言 本文主要是针对《Least-Squares Fitting of Two 3-D Point Sets》论文SVD求解旋转矩阵中推导过程中使用到的一些线性代数相关的内容做一些说明,具体算法实现不是很复杂,也有很多其他博客可以参考,比如参…
Robust fitting with bisquare weights uses an iteratively reweighted least-squares algorithm, and follows this procedure: Fit the model by weighted least squares. Compute the adjusted residuals and standardize them. The adjusted residuals are given by ri are the usual least-squares residuals and hi ar...
Noun1.least squares- a method of fitting a curve to data points so as to minimize the sum of the squares of the distances of the points from the curve method of least squares statistics- a branch of applied mathematics concerned with the collection and interpretation of quantitative data and...
Robust bisquare weights fitting uses the iteratively reweighted least-squares algorithm, which follows these steps: Fit the model by weighted least squares. For the first iteration, the algorithm uses weights equal to one unless you specify the weights. ...
Chebfun [18] is a MATLAB package for working with functions based primarily on polynomial interpolation, but it also provides basic routines for rational functions. In particular, theratinterpcommand runs a rational interpolation or least-squares fitting algorithm for the linearized equation (2.3), as...
