Optimal designs for estimating the coefficients of the lower frequencies in trigonometric regression models [PDF]
, 2005 In the common Fourier regression model we determine the optimal designs for estimating the coefficients corresponding to the lower frequencies. An analytical solution is provided which is found by an alternative characterization of c-optimal designs ...

OPTIMAL MODEL AVERAGING OF VARYING COEFFICIENT MODELS [PDF]
Statistica Sinica, 2019 We consider the problem of model averaging over a set of semiparametric varying coefficient models where the varying coefficients can be functions of continuous and categorical variables. We propose a Mallows model averaging procedure that is capable of delivering model averaging estimators with solid finite-sample performance.

Optimal Control Systems by Time-Dependent Coefficients Using CAS Wavelets
Journal of Applied Mathematics, 2009 This paper considers the problem of controlling the solution of an initial boundary-value problem for a wave equation with time-dependent sound speed. The control problem is to determine the optimal sound speed function which damps the vibration of the ...

Optimal designs for estimating individual coefficients in polynomial regression with no intercept [PDF]
, 2019 In a seminal paper Studden (1968) characterized c-optimal designs in regression models, where the regression functions form a Chebyshev system. He used these results to determine the optimal design for estimating the individual coefficients in a ...

Calculation of Coefficients of the Optimal Quadrature Formulas in
AxiomsIn this paper, we construct an optimal quadrature formula in the sense of Sard by Sobolev’s method in the W2(7,0) space. We give explicit expressions for the corresponding optimal coefficients.

Identification Problem for Nonlinear Gao Beam
Mathematics, 2020 This paper deals with the identification of coefficients in the nonlinear beam model which was first introduced by D. Y. Gao in 1996. For the identification of coefficients, an optimal control approach is used.

Convergence of quasi-optimal Stochastic Galerkin methods for a class of PDES with random coefficients [PDF]
, 2014 In this work we consider quasi-optimal versions of the Stochastic Galerkin method for solving linear elliptic PDEs with stochastic coefficients. In particular, we consider the case of a finite number $N$ of random inputs and an analytic dependence of the
