We consider polynomial approximation on the unit sphere S² = {(x, y, z) Є R³ : x² + y² + z² = 1} by a class of regularized discrete least squares methods with novel choices for the regularization ...
Least-Squares Galerkin Methods for Parabolic Problems III: Semidiscrete Case for Semilinear Problems
SIAM Journal on Numerical Analysis, Vol. 42, No. 6 (2005), pp. 2452-2475 (24 pages) This is the third part of a series of papers on least-squares Galerkin methods for parabolic initial-boundary value ...
The ARIMA procedure primarily uses the computational methods outlined by Box and Jenkins. Marquardt's method is used for the nonlinear least-squares iterations. Numerical approximations of the ...
Learn how the Least Squares Criterion determines the line of best fit for data analysis, enhancing predictive accuracy in finance, economics, and investing.
The element‐free Galerkin (EFG) methods represent a significant progression in numerical analysis, harnessing meshless techniques to overcome challenges associated with conventional meshing. By ...
Most straight-line approximations for data points are found using the method of least squares. This method works for many applications, but it cannot guarantee that the greatest vertical distance ...
