Understanding the Alias-Optimal design algorithm, optimization of a fixed block effect
I was wondering: when one adds a fixed block effect to the alias-optimal design, how is it optimized? For instance, following the explications by Jones and Nachtsheim(2011): is it optimized in the first objective being D-optimality optimization for the model terms, or, is it optimized in the secondary objective, being optimizing the orthogonality between Alias term and the model terms?.. or someth...
