Marginally restricted sequential D‐optimal designs

Canadian Journal of Statistics, 2008
AbstractIn many experiments, not all explanatory variables can be controlled. When the units arise sequentially, different approaches may be used. The authors study a natural sequential procedure for “marginally restricted” D‐optimal designs. They assume that one set of explanatory variables (x1) is observed sequentially, and that the experimenter ...

Soft selection in D-optimal designs

1994
A new algorithm generating the D-optimal experimental designs, based on an evolutionary search with soft selection, is presented. An efficiency of the numerical algorithm is compared with classical exchange algorithms. Preliminary results are promising and encourage more detailed investigations.

D‐optimal designs and group divisible designs

Journal of Combinatorial Designs, 2006
AbstractWe obtain new conditions on the existence of a square matrix whose Gram matrix has a block structure with certain properties, including D‐optimal designs of order $n\equiv 3 \pmod 4$, and investigate relations to group divisible designs. We also find a matrix with large determinant for n = 39. © 2006 Wiley Periodicals, Inc. J Combin Designs 14:

D-optimal designs on the unit q-ball

Journal of Statistical Planning and Inference, 1988
Abstract Consider a polynomial regression model on the unit q-ball. We can express the determinant of the information matrix in terms of canonical moments. Thus we can find the robust-type D-optimal designs in the sense of Stigler (1971) and Studden (1982).
