On weighted total least squares adjustment for solving the nonlinear problems
Journal of Geodetic Science, 2014 In the classical geodetic data processing, a non- linear problem always can be converted to a linear least squares adjustment. However, the errors in Jacob matrix are often not being considered when using the least square method to estimate the optimal ...

Parameter estimation using weighted total least squares in the two‐compartment exchange model
Magnetic Resonance in Medicine, 2018 PurposeThe linear least squares (LLS) estimator provides a fast approach to parameter estimation in the linearized two‐compartment exchange model. However, the LLS method may introduce a bias through correlated noise in the system matrix of the model.

Robust denoising-oriented point cloud plane fitting method based on a combined model of improved Cook’s distance and WTLS [PDF]
Journal of Intelligent Manufacturing and Special Equipment, 2022 Purpose – In order to improve the robustness to noise in point cloud plane fitting, a combined model of improved Cook’s distance (ICOOK) and WTLS is proposed by setting a modified Cook’s increment, which could help adaptively remove the noise points that

Comparison of straight line curve fit approaches for determining parameter variances and covariances
International Journal of Metrology and Quality Engineering, 2020 Pressure balances are known to have a linear straight line equation of the form y = ax + b that relates the applied pressure x to the effective area y, and recent work has investigated the use of Ordinary Least Squares (OLS), Weighted Least Squares (WLS),
