Adaptive experimental designs are sequential methods for gathering info. In every one step, the observer can use all the info amassed to figure out even if to prevent or keep it up with the examine. This publication specializes in lately constructed equipment in adaptive randomization for remedy allocation. It illustrates designs that bear in mind previous therapy allocations in simple terms, discusses techniques that use previous info, and offers compromise concepts that care for moral issues.

Example text

If the sequence {δn }n∈N is an irreducible and positive recurrent, Markov chain, there will exist a stationary distribution ξ. If the chain is also aperiodic, by the Law of Large Numbers for Markov chains the experiment will converge to ξ. In other words, the randomization procedure will tend to a target treatment allocation, which can be described as the asymptotic design. , 1972). 42) holds. 8. We stress that the Markovian designs briefly sketched here are introduced only as examples; their properties are studied at greater depth in Chapters 2 and 3.
