The method of least squares is a rigorous technique that can be applied to the adjustment of single traverses as well as networks of connected traverses to yield the most likely values of the survey measurements. Leahy () has an excellent summary of the theoretical basis and development of the least squares technique. Least-squares (approximate) solution • assume A is full rank, skinny • to ﬁnd xls, we’ll minimize norm of residual squared, krk2 = xTATAx−2yTAx+yTy • set gradient w.r.t. x to zero: ∇xkrk2 = 2ATAx−2ATy = 0 • yields the normal equations: ATAx = ATy • assumptions imply ATA invertible, so we have xls = (ATA)−1ATy a very famous formula.

Nonlinear Least Squares Data Fitting D.1 Introduction A nonlinear least squares problem is an unconstrained minimization problem of the form minimize x f(x)= m i=1 f i(x)2, where the objective function is deﬁned in terms of auxiliary functions {f i}.It is called “least squares” because we are minimizing the sum of squares of these functions.

The Least Squares Method Taken outside the context of the ML method, the least squares method is the most commonly known estimator. Errors in the Least Squares Method What about the errors and correlations between m and b? Simplest way to derive this is to look at the chi-squared, and. THE THEORY OF THE METHOD OF LEAST SQUARES THE THEORY OF THE METHOD OF LEAST SQUARES Thompson, E. H. Abstract This paper gives derivations of some of the more important results in the method of least squares in terms of matrix algebra. The following topics are covered: derivation of normal equations and their solution; residuals: estimation of standard errors.

The method of least squares is a standard approach in regression analysis to approximate the solution of overdetermined systems (sets of equations in which there are more equations than unknowns) by minimizing the sum of the squares of the residuals made in the results of every single equation.

The most important application is in data best fit in the least-squares sense minimizes.

Least squares method, also called least squares approximation, in statistics, a method for estimating the true value of some quantity based on a consideration of errors in observations or measurements. In particular, the line (the function y i = a + bx i, where x i are the values at which y i is measured and i denotes an individual observation) that minimizes the sum of the squared distances.

Additional Physical Format: Online version: Johnson, William Woolsey, Theory of errors and method of least squares. New York, J. Wiley & Sons, Abstract. The method of least squares was the cause of a famous dispute between two giants of the scientific world of the early 19 th century: Adrien Marie Legendre and Carl Friedrich Gauss.

The first published treatment of the method of least squares was included in an appendix to Legendre's book Nouvelles methods pour la determination des orbites des cometes. The most famous priority dispute in the history of statistics is that between Gauss and Legendre, over the discovery of the method of least squares.

New evidence, both documentary and statistical, is discussed, and an attempt is made to evaluate Gauss's claim. Ge lecture 1 (LEAST SQUARES ADJUSTMENT) by: Broddett B. Abatayo 1.
