Selection and Screening Procedures to Determine Optimal Product Designs. (REVISED, April 1997) [PDF]
, 1996 To compare several promising product designs, manufacturers must measure their performance under multiple environmental conditions. In many applications, a product design is considered to be seriously flawed if its performance is poor under any level of

Optimal Designs For the Restricted Maximum Likelihood Estimators in a Random Split-Plot Model
Lithuanian Journal of Statistics, 2017 The design effect for the restricted maximum likelihood estimators of variance components in acompletely randomized split-plot model is studied. The model was used to represent the response generated froman experimental scenario where the whole-plot and

Improved Split-Plot and Multistratum Designs [PDF]
Technometrics, 2015 Many industrial experiments involve some factors whose levels are harder to set than others. The best way to deal with these is to plan the experiment carefully as a split-plot, or more generally a multistratum, design. Several different approaches for constructing split-plot type response surface designs have been proposed in the literature since 2001,
