D-OPTIMAL EXACT DESIGNS FOR PARAMETER ESTIMATION IN A QUADRATIC MODEL
L. IMHOF, O. KRAFFT and M. SCHAEFER, Technical University of Aachen,
SUMMARY. We consider a quadratic regression model and derive D-optimal exact designs for estimating any given subset of the model parameters. Our results complete recent findings of Krafft and Schaefer (1995) and of Gaffke and Krafft (1982).
AMS (1991) subject classification. Primary 62K05; secondary 62J05.
Key words and phrases. DA-optimality, quadratic regression, exact design theory, singular information matrices.
