RISAn Improved Weighted Total Least Squares Method with Applications in Linear Fitting and Coordinate Transformation
Publisher: American Society of Civil Engineers
Abstract: This paper presents an improved weighted total least squares (IWTLS) method for the errors-in-variables (EIV) model with applications in linear fitting and coordinate transformation. In addition, an improved constrained ...
Partial Total-Least-Squares Adjustment of Condition Equations with Application to a Rectangular Building Adjustment in a GIS
Publisher: American Society of Civil Engineers
Abstract: This paper presents a partial total-least-squares adjustment method for condition equations (PTLSC) in which the observation vector and coefficient matrix contain linearly correlated errors. In the proposed method, the ...
