摘要：Multistratum design arises naturally in industrial experiments due to the inconvenient and impractical completely randomization. Most research has concentrated on finding optimal multistratum designs that have high efficiencies in parameter estimation. Accounting for the model uncertainty, we apply the Bayesian model averaging method and predictive approach to investigate the optimization problem for data with multi-stratum structure. With the posterior probabilities of models as weights, we consider the weighted average of the predictive densities of the response over all potential models. The goal of the optimization is to identify the values of the factors that result in a maximum probability of a response in a given range. The method is illustrated with two examples.
