D-optimal mixed level arrays
The Orthogonal Array (OA) package is a software package to generate and analyse orthogonal arrays and optimal designs.
On this page you can generate designs with a specified number of runs, factors and factor-levels. The designs are generated using a coordinate-exchange algorithm to optimize the \(D\)-efficiency. After generation of the designs the best designs are selected according to Pareto optimality of the \(D\), \(D_s\) and \(D_1\)-efficiency.
If you make use of the software included in the package, please cite the following paper: Two-Level Designs to Estimate All Main Effects and Two-Factor Interactions, Technometrics, 2016.
