has been combined with a least squares adjustment package. The options have been implemented to accept an input of both weighted parameters and functional parameter constraints. Chapter 2 Least Squares Rules вЂќGiven a set of observations, which model parameters gives a model which approxi-mates those up to the smallest sum of squared residuals?вЂќ

Let then the weighted least squares estimator of is obtained by solving normal equation which gives where are called the weights. The observations with large variances usual have smaller weights than observations with small variance.. The general subject of errors in measurement was discussed in Chapter 2, and the two classes of errors, systematic and random (or accidental), were defined. It was noted that systematic errors follow physical laws, and that if the conditions producing them are measured, corrections to eliminate.

Least-Squares Parameter Estimation in Linear Models Recursive least-squares state-space estimation is based on the reformulation of the least-squares estimation using all available observation data; see, e. g., Koch (1999)..

Keywords: Least squares, least squares collocation, Kalman filter, total least squares, adjustment computation 1. Introduction Surveying measurements are usually compromised by errors in field observations and therefore require mathematical adjustment [1]. In the first half of the 19th century the Least Squares (LS) [2] adjustment technique was developed. LS is the conventional technique for. Each term in the weighted least squares criterion includes an additional weight, that determines how much each observation in the data set influences the final parameter. In the second algorithm, a multi-photo least squares matching model is added to the adjustment. In this model, observation equations are formed to quantify the.
