This paper shows the current interest in the problem in biostatistical applications. Since biostatistical trials can be (and often are) run in stages, a two-stage procedure would be relatively easy to apply in that setting.

There are many papers continuing to study the approximate procedures; about none of them seem to be aware of the exact solutions (else, why would they bother?). Approximations may still be of interest when two stages is not a possibility, but that case is not as common as needed to justify the lack of consideration in these “approximation” papers. Also, one-stage versions of two-stage procedures are another line of research some are pursuing with some success. Such work for the procedure of the present paper we have presented is an open problem.
