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.
