Multiple randomizations
Multitiered experiments are characterised by involving multiple
randomizations, in a sense that we make explicit. We compare and contrast
six types of multiple randomizations, using a wide range of examples, and
discuss their use in designing experiments. We outline a system of
describing the randomizations in terms of sets of objects, their
associated tiers and the factor nesting, using randomization diagrams,
which give a convenient and readily assimilated summary of an experiment's
randomization. We also indicate how to formulate a randomization-based
mixture model for the analysis of data from such experiments.
