Using an Equivalence Theorem and the theory of Sturm Liouville systems, we determine the D-optimal designs for some classes of weighted polynomial regression of degree d on the interval [-1., 1]. We also show that the number of the optimal support points for such models is d+ 1. and that the optimal

β¦ Synopsis
In this article we consider D-optimal designs for polynomial regression models with low-degree terms being missed, by applying the theory of canonical moments. It turns out that the optimal design places equal weight on each of the zeros of some Jacobi polynomial when the number of unknown parameters in the model is even. The procedure and examples of ΓΏnding the optimal supports and weights are given when the number of unknown parameters in the model is odd.

By utilizing the equivalence theorem and Descartes's rule of signs, we construct D-optimal designs for a weighted polynomial regression model of degree k, with speciΓΏc weight function w(x) = 1=(a 2 -x 2 ) , on the compact interval [ -1; 1]. The main result shows that in most cases, the number of sup
In this work, the exact D-optimal designs for weighted polynomial regression are investigated. In Ga ke (1987, J. Statist. Planning Inference 15, 189 -204) a su cient condition has been given that Salaeveski Γ i's type of result about the exact D-optimal designs holds when sample size n is large eno

We consider the Bayesian D-optimal design problem for exponential growth models with one. two or three parameters. For the one-parameter model conditions on the shape of the density of the prior distribution and on the range of its support are given guaranteeing that a one-point design is also Bayes
We give the E-optimal approximate designs for mean (sub-) parameters in dth degree totally positive polynomial spline regression with prescribed knots over an arbitrary compact real interval. Based on a duality between E-and scalar optimality, the optimal design is found to be supported by the extre
