Testing the suitability of polynomial models in errors-in-variables problems [PDF]

open access: yes, 2007
A low-degree polynomial model for a response curve is used commonly in practice. It generally incorporates a linear or quadratic function of the covariate.

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.

Regression quantiles with errors-in-variables [PDF]

open access: yesJournal of Nonparametric Statistics, 2009
Abstract In a lot of situations, variables are measured with errors. While this problem has been previously studied in the context of kernel regression, no work has been done in quantile regression. To estimate this function, we use deconvolution kernel estimators.

Errors in Variables in Panel Data [PDF]

open access: yesJournal of Econometrics, 1986
Abstract Panel data based studies in econometrics use the analysis of covariance approach to control for various ‘individual effects’ by estimating coefficients from the ‘within’ dimension of the data. Often, however, the results are unsatisfactory, with ‘too low’ and insignificant coefficients.

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 ...

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 ...

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 ...

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.

Empirical Likelihood Confidence Region for Parameters in Semi-linear Errors-in-Variables Models [PDF]

open access: yes, 2006
This paper proposes a constrained empirical likelihood confidence region for a parameter in the semi-linear errors-in-variables model. The confidence region is constructed by combining the score function corresponding to the squared orthogonal distance

On errors-in-variables estimation with unknown noise variance ratio [PDF]

open access: yes, 2006
We propose an estimation method for an errors-in-variables model with unknown input and output noise variances. The main assumption that allows identifiability of the model is clustering of the data into two clusters that are distinct in a certain ...
