First-Order 'Interruptable' Designs
Abstract
Even a well-designed experiment interrupted before its intended completion may prove inefficient, posing serious data analysis problems and leaving important questions unanswered. This report addresses the construction of 'interruptable' designs for those cases where a first-order model is assumed and factors at only two levels are considered. The maximum absolute value (X'X) criterion was used in developing 'interruptable' designs for two different design strategies which attempt to limit the information lost if an experiment is prematurely ended. The resulting designs for four to nine factors are evaluated and selection of an 'interruptable' design is discussed.
