In a two-level factorial experiment, the authors consider designs with partial duplication which permit estimation of the constant term, all main effects and some specified two-factor interactions, ...

Experimentation is a vital part of the scientific method. Most problems in science require observation of the system at work and experimentation to elucidate information about how the system works. In ...

Mitchell and Bayne use an exchange algorithm to develop some new experimental designs in five and fewer factors. The properties of these designs are examined. While these designs have high ...
