Adaptive experimental designs are sequential techniques for accumulating facts. In each one step, the observer can use all the info accrued to figure out no matter if to prevent or stick with it with the examine. This booklet specializes in lately built equipment in adaptive randomization for remedy allocation. It illustrates designs that bear in mind earlier remedy allocations basically, discusses approaches that use earlier info, and provides compromise ideas that take care of moral issues.

In the urn designs, at every step the treatment allocation is randomized by selecting a ball at random from an urn containing a given number of balls of several types, one for each available treatment: when a ball of a given type is drawn, the corresponding treatment gets assigned. The evolution of the urn is governed by the so-called addition rule, which specifies i) whether the chosen ball will be replaced in the urn or not and ii) how many balls of each type will be added, if any, to the urn.
