Least squares approximations of power series
The classical least squares solutions in C[−1,1] in terms of linear combinations of ul-traspherical polynomials are extended in order to estimate power series on (−1,1). Approximate rates of uniform and pointwise convergence are obtained, which correspond to recent results of U. Luther and G. Mastroianni on Fourier projections with respect to Jacobi polynomials.
متن کاملExtrapolating time series by discounted least squares
An approximating function is fitted to a time series, such as daily observation. The fitting is carried out over all past time by weighted least squares with an exponential weight factor• The approximating function is restricted to be a solution of a certain linear differential equation of the mth order having constant coefficients. The solution which minimizes the least square expression can b...
متن کاملThe approximation power of moving least-squares
A general method for near-best approximations to functionals on Rd, using scattered-data information is discussed. The method is actually the moving least-squares method, presented by the Backus-Gilbert approach. It is shown that the method works very well for interpolation, smoothing and derivatives’ approximations. For the interpolation problem this approach gives Mclain’s method. The method ...
متن کاملLeast-squares Finite Element Approximations to Solutions of Interface Problems∗
A least-squares finite element method for second-order elliptic boundary value problems having interfaces due to discontinuous media properties is proposed and analyzed. Both Dirichlet and Neumann boundary data are treated. The boundary value problems are recast into a firstorder formulation to which a suitable least-squares principle is applied. Among the advantages of the method are that nonc...
متن کاملOn the Stability and Accuracy of Least Squares Approximations
We consider the problem of reconstructing an unknown function f on a domain X from samples of f at n randomly chosen points with respect to a given measure ρX . Given a sequence of linear spaces (Vm)m>0 with dim(Vm) = m ≤ n, we study the least squares approximations from the spaces Vm. It is well known that such approximations can be inaccurate when m is too close to n, even when the samples ar...
