Multiple Linear Regression: The Equivalence of Least Squares & Covariance. In these notes we will address the linear model (1.0) Specifically, we will compare the least squares (LS) solution and the theoretical covariance solution for the model parameters. 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].

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.

A regression or least-squares fit, which is a straight line of the type shown in Figure 2, is then made to the data. The regression fit corresponds to the range dependence A/Rn, where A is an amplitude constant and n is the slope index. For two antennas located in free space, the value of n is 2.
