Abstract: Factorial designs with randomization restrictions are often used in industrial experiments when complete randomization of trials is impractical. In the statistics literature, the analysis, construction and isomorphism of factorial designs have been extensively investigated. Much… read more here.

Abstract: Moderation analysis is a vital aspect of research in education, management, psychology, and related disciplines. Although several methodological artifacts have been identified and examined, heterogeneity of variance remains one of the unique and problematic factors… read more here.

Abstract: ABSTRACT Replicating runs in designed experiments is good practice. The most important reason to replicate runs is to allow for a model-independent estimate of the error variance. Without the pure error degrees of freedom provided… read more here.
