博士 === 國立成功大學 === 統計學系碩博士班 === 91 === Consider the problem of discriminating between two
rival polynomial regression models on the q-cube
[-1,1]^q, qεN, or two rival Fourier regression
models on the circle [-π,π], and estimating
parameters in the models. In order to find
experimental designs which are efficient for both
purposes of model discrimination and parameter
estimation simultaneously, we propose a general
multiple-objective optimality criterion,
Mr-optimality criterion, which is a weighted
geometric average of D- and Ds-efficiencies, it
puts weight r (0≦r≦1) for model discrimination
and (1-r) for parameter estimation.
The corresponding Mr-optimal design is explicitly
derived in terms of canonical moments. Moreover,
the behavior of the proposed Mr-optimal designs
is investigated under different weighted selection
criterion. Furthermore, applying the maximin
principle on the efficiencies of experimental
designs, the extreme value of the minimum
Mr-efficiency of any Mr''-optimal design is obtained
at r''=r*, which results in the corresponding
Mr*-optimal design to be served as a criterion-
robust optimal design for the described problem.
