摘要：In the clinical trial randomized play-the-winner rule is used with
a goal to allocate more patients to the better treatment in course of sampling.
Here we provide an application of this sampling scheme in repeated measurement
design. We concentrate on the simplest set up, i.e., on two treatments
and two periods. We study, both numerically and theoretically, several exact
and limiting properties of this design. We consider some related inferential
problems. Finally we use a real data set to illustrate the applicability of our
proposed design.
