Abstract:Abstract:The author discusses integer-valued designs for wavelet estimation of nonparametric response curves in the possible presence of heteroscedastic noise using a modified wavelet version of the GasserMüller kernel estimator or weighted least squares estimation. The designs are constructed using a minimax treatment and the simulated annealing algorithm. The author presents designs for three case studies in experiments for investigating Gompertz's theory on mortality rates, nitrite utilization in bush beans… Show more
“…In recent years, various linear and approximately linear wavelet models and their optimal designs have been studied. [5][6][7][8][11][12][13][14] A wavelet system on the real line R was discovered by Haar. 3 The system is an orthogonal basis in L 2 (R) generated by the Haar scaling function and the Haar primary wavelet.…”
Estimations and optimal experimental designs for two-dimensional Haar-wavelet regression models are discussed. It is shown that the eigenvalues of the covariance matrix of the best linear unbiased estimator of the unknown parameters in a two-dimensional linear Haar-wavelet model can be represented in closed form. Some common discrete optimal designs for the model are constructed analytically from the eigenvalues. Some equivalences among these optimal designs are also given, and an example is demonstrated.
