Abstract:

The ethical motivation comes the criterion that expects m ore patients to be allocated in the superior treatment in the clinical trials. B ased on minimization of error probability, a kind of asymptotic optimal design i n urn models has been constructed. By this design, not only more patients may ex pect to be assignned in the superior treatment, but also the estimates of succes s probabilites posses asymptotical statistical efficiency in some sence.

Key words: Urn model, Sequential experiment, Strong consistency, Asmptotic normatity, Efficiency, Error probability, Optimal design
