Article Abstract

[This abstract is based on the author's abstract.] The DETMAX algorithm is presented. Its purpose is to construct experimental designs that are D-optimal. These are designs for which the determinant of X'X is maximum, where X is the matrix of independent variables in the usual linear model y = Xb + e. Although the algorithm does not guarantee D-optimality, it has performed well in many cases where D-optimal designs are known. Five examples are given, illustrating the use of DETMAX to construct designs from scratch and to augment existing data. A FORTRAN listing is available on request.
