NettetIn [Teunissen, 2003] we described the general principle of integer aperture (IA) ambiguity estimation. In the present contribution we introduce one particular IA estimator, the integer aperture least-squares (IALS) estimator. The motivation for studying this estimator stems from the known optimality of the integer least-squares estimator. Nettet1. jul. 2024 · This study adopts ordinary least square and quantile reg...

Nettet12. nov. 2013 · The integer least squares (ILS) problem, also known as the weighted closest point problem, is highly interdisciplinary, but no algorithm can find its global optimal integer solution in polynomial time. We first outline two suboptimal integer solutions, ... NettetThe integer least squares problem arises from many ap-plications: communications [4], cryptography [1], GPS [3], to name a few, where the solution x to be found is a code …
NettetIt is shown that the integer least-squares principle maximizes the probability of correct integer estimation. Sharp and easy-tocompute bounds are given for both the ambiguity … Nettet15. nov. 2004 · With this estimator, the propagated variance-covariance matrix of the estimated parameters can be obtained. We have adapted the LAMBDA method, part of an integer least squares estimator developed for the ambiguity resolution of carrier phase observations in global positioning systems, to the problem of permanent scatterers.

The linear least-squares problem occurs in statistical regression analysis; it has a closed-form solution. Se mer 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 … Se mer This regression formulation considers only observational errors in the dependent variable (but the alternative total least squares regression can account for errors in both variables). There are two rather different contexts with different implications: Se mer Consider a simple example drawn from physics. A spring should obey Hooke's law which states that the extension of a spring y is proportional to the force, F, applied to it. Se mer In a least squares calculation with unit weights, or in linear regression, the variance on the jth parameter, denoted $${\displaystyle \operatorname {var} ({\hat {\beta }}_{j})}$$, … Se mer Founding The method of least squares grew out of the fields of astronomy and geodesy, as scientists and … Se mer The objective consists of adjusting the parameters of a model function to best fit a data set. A simple data set consists of n points (data pairs) $${\displaystyle (x_{i},y_{i})\!}$$, i = 1, …, n, where $${\displaystyle x_{i}\!}$$ is an independent variable Se mer The minimum of the sum of squares is found by setting the gradient to zero. Since the model contains m parameters, there are m gradient equations: The gradient equations apply to all least squares problems.
