Split-plot x Split-block type three factor designs

摘要

We consider modelling and some construction methods of incomplete split-plot x split-block designs for three factor experiments. In the modelling we take into account a structure of an experimental material and a four-step randomization schema. We adopt the approach typical to multistratum experiments with orthogonal block structure with respect to the analysis of the obtained randomization model with seven strata. A brief discussion connected with the method of the construction of the design is given.
