A delimitation of the support of optimal designs for Kiefer's $\phi_p$-class of criteria [PDF]

open access: yes, 2013
The paper extends the result of Harman and Pronzato [Stat. & Prob. Lett., 77:90--94, 2007], which corresponds to $p=0$, to all strictly concave criteria in Kiefer's $\phi_p$-class.

A geometric characterization of $c$-optimal designs for heteroscedastic regression [PDF]

open access: yes, 2008
We consider the common nonlinear regression model where the variance, as well as the mean, is a parametric function of the explanatory variables. The $c$-optimal design problem is investigated in the case when the parameters of both the mean and the ...

Complete classes of designs for nonlinear regression models and principal representations of moment spaces [PDF]

open access: yes, 2012
In a recent paper Yang and Stufken [Ann. Statist. 40 (2012a) 1665-1685] gave sufficient conditions for complete classes of designs for nonlinear regression models. In this note we demonstrate that there is an alternative way to validate this result.

Robust T-optimal discriminating designs [PDF]

open access: yes, 2012
This paper considers the problem of constructing optimal discriminating experimental designs for competing regression models on the basis of the T-optimality criterion introduced by Atkinson and Fedorov [Biometrika 62 (1975) 57-70].

Optimal designs for comparing curves [PDF]

open access: yes, 2014
We consider the optimal design problem for a comparison of two regression curves, which is used to establish the similarity between the dose response relationships of two groups.

Generalized wordlength patterns and strength

open access: yes, 2012
Xu and Wu (2001) defined the \emph{generalized wordlength pattern} $(A_1, ..., A_k)$ of an arbitrary fractional factorial design (or orthogonal array) on $k$ factors.

Universal optimality of Patterson's crossover designs

open access: yes, 2006
We show that the balanced crossover designs given by Patterson [Biometrika 39 (1952) 32--48] are (a) universally optimal (UO) for the joint estimation of direct and residual effects when the competing class is the class of connected binary designs and (b)

Optimum Choice of Covariates for a Series of SBIBDS Obtained Through Projective Geometry [PDF]

open access: yes, 2007
A block design set up is considered in presence of a number of controllable covariates. The problem is that of choosing the values of the covariates so that for a given block design, it is optimum in the sense of attaining minimum variance for the ...

Optimum design accounting for the global nonlinear behavior of the model [PDF]

open access: yes, 2014
Among the major difficulties that one may encounter when estimating parameters in a nonlinear regression model are the nonuniqueness of the estimator, its instability with respect to small perturbations of the observations and the presence of local ...
