Title: Generalized Bayesian D criterion for single-stratum and multistratum designs Authors:  Chang-Yun Lin - National Chung Hsing University (Taiwan) [presenting]
Abstract: DuMouchel and Jones proposed the Bayesian D criterion by modifying the D-optimality approach to reduce dependence of the selected design on an assumed model. This criterion has been applied to select various single-stratum designs for completely randomized experiments when the number of effects is greater than the sample size. In many industrial experiments, complete randomization is sometimes expensive or infeasible and, hence, designs used for the experiments often have multistratum struc- tures. However, the original Bayesian D criterion was developed under the framework of single-stratum structures and cannot be applied to select multistratum designs. In this paper, we study how to extend the Bayesian approach for more complicated exper- iments and develop the generalized Bayesian D criterion, which generalizes the original Bayesian D criterion and can be applied to select single-stratum and multistratum de- signs for various experiments when the number of effects is greater than the rank of the model matrix.
