Errors in Variables in Linear Systems [PDF]

open access: yesEconometrica, 1987
This paper extends the simple errors-in-variables bound to the setting of systems of equations. Both diagonal and nondiagonal measurement error covariance matrices are considered. In the nondiagonal case, the analogue of the simple errors-in-variables interval of estimates is an ellipsoid with diagonal equal to the line segment connecting the direct ...

Solution for a time-series AR model based on robust TLS estimation

open access: yesGeomatics, Natural Hazards & Risk, 2019
We discuss an algorithm for the autoregression (AR) model as a typical time-series model. By analyzing the structure of the AR model, we highlight the shortcomings of traditional algorithms for model parameter estimation and propose an approach to ...

Testing straightness of line objects using total least squares [PDF]

open access: yesTehnika, 2017
The paper presents the adaptation (fitting) of a set of points, with an estimated two-dimensional positions, to the straight line model of the by the application of the Weighted Total Least Squares, WTLS.

Errors-in-Variables Models [PDF]

open access: yes, 2000
Errors-in-variables (EIV) models axe regression models in which the regres-sors axe observed with errors. These models include the linear EIV models, the nonlinear EIV models, and the partially linear EIV models. Suppose that we want to investigate the relationship between the yield (Y) of corn and available nitrogen (X) in the soil.

Nonparametric Regression with Errors in Variables

open access: yesThe Annals of Statistics, 1993
The effect of errors in variables in nonparametric regression estimation is examined. To account for errors in covariates, deconvolution is involved in the construction of a new class of kernel estimators. It is shown that optimal local and global rates of convergence of these kernel estimators can be characterized by the tail behavior of the ...

An Overview of Linear Structural Models in Errors in Variables Regression

open access: yesRevstat Statistical Journal, 2010
This paper aims to overview the numerous approaches that have been developed to estimate the parameters of the linear structural model. The linear structural model is an example of an errors in variables model, or measurement error model that has wide ...

On The Errors-In-Variables Model With Singular Dispersion Matrices

open access: yesJournal of Geodetic Science, 2014
While the Errors-In-Variables (EIV) Model has been treated as a special case of the nonlinear Gauss- Helmert Model (GHM) for more than a century, it was only in 1980 that Golub and Van Loan showed how the Total Least-Squares (TLS) solution can be ...

Asymptotic normality of total least squares estimator in a multivariate errors-in-variables model AX=B

open access: yesModern Stochastics: Theory and Applications, 2016
We consider a multivariate functional measurement error model $AX\approx B$. The errors in $[A,B]$ are uncorrelated, row-wise independent, and have equal (unknown) variances.

Errors-in-Variables Estimation with Wavelets

open access: yesSSRN Electronic Journal, 2009
This paper proposes a wavelet (spectral) approach to estimate the parameters of a linear regression model where the regressand and the regressors are persistent processes and contain a measurement error. We propose a wavelet filtering approach which does not require instruments and yields unbiased estimates for the intercept and the slope parameters ...

Discrimination of Geological Orientation Data with Measurement Errors

open access: yesStats
Fracture orientation data in structural geology are commonly affected by non-negligible angular uncertainty, which can significantly impact the reliability of classification and interpretation of deformation patterns. In this work, we address the problem
