      Least-squares regression. Least-squares regression refers to problems of the form. where is an (n x 1) vector of parameters over which the minimization is performed and xi, wi are the problem data, xi being a scalar and wi an (1 x n) vector, often referred to as the “regressor” vector.

      1. Fit a linear regression trend line – plot the scatterplot and show the linear regression line going through the scatterplot. 2. You notice that there are some outliers that clearly influence the fit. To remedy this you decide to perform a ‘weighted least squares’. Described in page 280-285 of Helsel and Hirsch book (Chapter 10).

      5.4 Multiple Linear Regression: The Equivalence of Least Squares & Covariance. Consider the linear model (5.4.1) Specifically, we will compare the least squares (LS) solution and the theoretical covariance solution for the model parameters. The Least Squares Method: The method of LS typically is framed in relation to data; not random variables.

      The usual non-weighted case corresponds to (identity matrix). Ordinary weighted least-squares (2) are commonly used to solve regression problems with noisy data [12], and in "iteratively re-weighted least-squares" procedures for computing robust regression statistics such as M-estimators [2][7].
