Title: On the Optimal Design of Comparative Experiments and the odw R Package
Abstract:
The optimal design of experiments has enjoyed a rich theoretical development, with elements dating back to 1918. While able to reproduce (or validate the properties of) classical experimental designs, the technology is particularly useful for constructing designs in non-standard situations. The notion of optimality is situation dependent, and this discussion is grounded in the design of categorical experiments in the agro-biological sciences. This talk describes an R package ODW that formalises design construction through the explicit specification of the respective linear (mixed) model. Some illustrations of its use are drawn from novel design applications, including designs which use various forms of correlated treatment effects, reduced animal models for generating designs with large numbers of treatments where the focus is optimality for additive effects of treatments and multi-phase experiments.
Best wishes,
Clara Grazian
