Linear least squares (LLS) is the least squares approximation of linear functions to data. It is a set of formulations for solving statistical problems involved in linear regression, including variants for ordinary (unweighted), weighted, and generalized (correlated) residuals.

2015年10月3日 · Ordinary Least Squares (OLS) - In its stochastic model assumes IID white noise. Linear Least Squares (LLS) - Allows white noise with different parameters per sample or correlated noise (Namely can have the form of Weighted Least squares). Total Least Squares and PCA are the ones which minimize the "Shortest" distance (Perpendicular distance).
