A Polynomial Fitting Problem: The Orthogonal Distances Method
Mathematics, 2022 The classical curve-fitting problem to relate two variables, x and y, deals with polynomials. Generally, this problem is solved by the least squares method (LS), where the minimization function considers the vertical errors from the data points to the ...

Performance evaluation of the Ordinary Least Square (OLS) and Total Least Square (TLS) in adjusting field data: an empirical study on a DGPS data [PDF]
South African Journal of Geomatics, 2017 Survey measurements have become the traditional means of obtaining point positions by most surveyors over the centuries. The assertion that a post processed DGPS field data is precise, accurate and can be used to execute any engineering works due to its minimum human errors need to be reviewed; this is because the post processed field data still ...

An improved mixed total least squares method for strain inversion from distance changes
Geodesy and Geodynamics, 2016 Based on the deficiency of the traditional total least squares method (TLS) in the field of geodetic inversion, the mixed error characteristics of the errors in variables (EIV) model were analyzed by considering the distance azimuth measurement error in ...

Total Least Squares (TLS) im Kontext der Ausgleichung nach kleinsten Quadraten am Beispiel der ausgleichenden Geraden [PDF]
ZFV (Augsburg), 2008 In diesem Beitrag wird eine ausgleichende Gerade in der Ebene behandelt, bei der beide Koordinatenkomponenten mit zufälligen Fehlern behaftete Messgrößen sind. Es wird gezeigt, dass eine sachgerechte Anwendung der Methode der kleinsten Quadrate dasselbe Ergebnis liefert wie die entsprechende Anwendung von Total Least Squares (TLS), da in beiden Fällen ...

Model estimation of cerebral hemodynamics between blood flow and volume changes: a data-based modeling approach [PDF]
, 2008 It is well known that there is a dynamic relationship between cerebral blood flow (CBF) and cerebral blood volume (CBV). With increasing applications of functional MRI, where the blood oxygen-level-dependent signals are recorded, the understanding and ...
