Designs in Five and Six Components for Mixtures Models with Inverse Terms.
Abstract
Briefly reviewed are the polynomial plus inverse terms mixture models, and the approximately D-optimal (measure) and D sub n-optimal (exact) designs for these models in three and four components. The use of Atwood's (1973) improvement to Fedorov's D-optimality algorithm is reviewed and further improvements are suggested. In addition, design region and model symmetry, and a simplified procedure for re-distributing design measure, are used to obtain measure designs in five and six components. Finally, exact designs are obtained from these measure designs.
